Problemas with LCD Menu

Projects Programming
1

Gentlemen good night!
I started playing with Arduino just a few weeks (as a hobby) and I'm loving it! Well, let my doubt. I found this library to create menus in the Playground LCD,GitHub - DavidAndrews/Arduino_LCD_Menu: This library creates menu systems primarily useful for 16x2 or 16x4 LCD displays. (which by the way I thought fantastic!) But I'm getting a strange behavior.

Since the whole program itself works fine, I'll just post the code to create the menu.
This is the menu structure that works 100%. Without "redrawn" behavior:

The menu tree is:

Light Sensors
  - On
  - Off
  - Back
Lights
  - Balcony Lights
    - On
    - Off
    - Back
Temperature

Code:

void setupMenus()
{  
  g_menuLCD.MenuLCDSetup();
  MenuEntry * p_menuEntryRoot;
  p_menuEntryRoot = new MenuEntry("Sensores Luz", NULL, NULL);
  g_menuManager.addMenuRoot( p_menuEntryRoot );
  g_menuManager.addChild( new MenuEntry("Ligar", (void *) (&sensorLuz), MenuEntry_BoolTrueCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Desligar", (void *) (&sensorLuz), MenuEntry_BoolFalseCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Voltar", (void *) &g_menuManager, MenuEntry_BackCallbackFunc) );
  //Crio o menu Luzes
  g_menuManager.addSibling( new MenuEntry("Luzes", NULL, NULL ) );
  g_menuManager.MenuDown(); //Vou "para baixo" do menu luzes
  //Adiciono o filho do menu luzes
  g_menuManager.addChild( new MenuEntry("Luz da Varanda", NULL, NULL ) );
  g_menuManager.MenuDown(); //Vou pra baixo do item luz da varanda
  g_menuManager.MenuSelect(); //seleciono o menu
  //adiciono os filhos
  g_menuManager.addChild( new MenuEntry("Ligar", (void *) (&luzVaranda), MenuEntry_BoolTrueCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Desligar", (void *) (&luzVaranda), MenuEntry_BoolFalseCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Voltar", (void *) &g_menuManager, MenuEntry_BackCallbackFunc) );
  
  //Volto para o menu principal para adicionar mais filhos
  g_menuManager.SelectRoot();
  //adiciono o menu filho para verificar a temperatura  
  g_menuManager.addSibling( new MenuEntry("Temperatura", (void *) (&mostraTemp), MenuEntry_BoolTrueCallbackFunc));
  g_menuManager.DrawMenu();
}

Now, this is the menu structure that causes the "redrawn" behavior. I only added one more subitem for menu:

Menu tree:

Light Sensors
  - On
  - Off
  - Back
Lights
  - Balcony Lights
    - On
    - Off
    - Back
  - Garage Lights    <---- The new subitem with childrens
    - On
    - Off
    - Back
Temperature

void setupMenus()
{  
  g_menuLCD.MenuLCDSetup();
  MenuEntry * p_menuEntryRoot;
  p_menuEntryRoot = new MenuEntry("Sensores Luz", NULL, NULL);
  g_menuManager.addMenuRoot( p_menuEntryRoot );
  g_menuManager.addChild( new MenuEntry("Ligar", (void *) (&sensorLuz), MenuEntry_BoolTrueCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Desligar", (void *) (&sensorLuz), MenuEntry_BoolFalseCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Voltar", (void *) &g_menuManager, MenuEntry_BackCallbackFunc) );
  //Crio o menu Luzes
  g_menuManager.addSibling( new MenuEntry("Luzes", NULL, NULL ) );
  g_menuManager.MenuDown(); //Vou "para baixo" do menu luzes
  //Adiciono o filho do menu luzes
  g_menuManager.addChild( new MenuEntry("Luz da Varanda", NULL, NULL ) );
  g_menuManager.MenuDown(); //Vou pra baixo do item luz da varanda
  g_menuManager.MenuSelect(); //seleciono o menu
  //adiciono os filhos
  g_menuManager.addChild( new MenuEntry("Ligar", (void *) (&luzVaranda), MenuEntry_BoolTrueCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Desligar", (void *) (&luzVaranda), MenuEntry_BoolFalseCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Voltar", (void *) &g_menuManager, MenuEntry_BackCallbackFunc) );

  // Here the new subiten withe their children

  //Adiciono novo item de menu abaixo de luzes
  g_menuManager.addSibling( new MenuEntry("Luz Garagem", NULL, NULL ) );
  g_menuManager.MenuDown(); //Vou pra baixo do item luz da varanda
  g_menuManager.MenuSelect(); //seleciono o menu
  //adiciono os filhos
  g_menuManager.addChild( new MenuEntry("Ligar", (void *) (&luzGaragem), MenuEntry_BoolTrueCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Desligar", (void *) (&luzGaragem), MenuEntry_BoolFalseCallbackFunc ) );
  g_menuManager.addChild( new MenuEntry("Voltar", (void *) &g_menuManager, MenuEntry_BackCallbackFunc) );  

 // Finish of the problematic subitem

  //Volto para o menu principal para adicionar mais filhos
  g_menuManager.SelectRoot();
  //adiciono o menu filho para verificar a temperatura  
  g_menuManager.addSibling( new MenuEntry("Temperatura", (void *) (&mostraTemp), MenuEntry_BoolTrueCallbackFunc));
  g_menuManager.DrawMenu();
}

What am I doing wrong? Has anyone used this library?

Note: Just remember that regardless of this behavior, the two menu code works perfectly.
Note2: Sorry bad english... it's rusty... :blush:
Note3: I made this little video in order to show the problem: - YouTube
Note4: For this post is not only questions (my first!), I made this little application to help create custom characters for LCD. I hope it's useful! It's hosted in my domain. http://danielcordeiro.eti.br/index.php/downloads/arduino-char/
