I have it on all cases .

  // ++++++++++++++++++++++++++++++++  menu ++++++++++++++++++++++++++++++++
  if (digitalRead(PA15) == 0)
  {
    // botonState = (botonState + 1) % 3;
    botonState = (botonState + 1) % 7;
    delay (200);
  }

  // lcd.print("               ");
  //display.setCursor(0, 0);
  // lcd.setCursor(0, 0);

  lcd.setCursor(0, 0);
  switch (botonState)
  {
    case 0:                                  // VDI
      lcd.print("#0 VDI ");
      lcd.setCursor(8, 0);
      lcd.print("min ");
      lcd.setCursor(8, 0);
      lcd.print("min ");
      lcd.setCursor(12, 0);
      lcd.print("max");
      break;

    case 1:                            //Ubal, amp, shift
      lcd.print("#1 B ");
      lcd.print(UbalmV, 0);
      lcd.print("         ");
      lcd.setCursor(0, 1);
      lcd.print("a ");
      lcd.print( amp    );
      lcd.setCursor(10, 1);
      lcd.print("f ");
      lcd.print( shift);
      digitalWrite(PC13, LOW);
      digitalWrite(PA7,  HIGH);
      digitalWrite(PB0, HIGH);
      break;

    case 2:                                 // Threshold
      //lcd.print("         ");
      lcd.print("#2 M ");           //  2
      lcd.println(Magn);         // PA1,PA2
      lcd.setCursor(10, 0);
      lcd.print("T ");           //  48
      lcd.println(t);
      lcd.setCursor(0, 1);
      lcd.print("                 ");
      digitalWrite(PC13, HIGH);
      digitalWrite(PA7, LOW);
      digitalWrite(PB0, HIGH);
      //lcd.println( "                                   ");
      break;

    case 3:                            // Z
      lcd.print("#3 Z ");
      lcd.println(z);
      digitalWrite(PC13, HIGH);
      digitalWrite(PA7, HIGH);
      digitalWrite(PB0, LOW);

      break;
    case 4:                         // AV, A
      lcd.print("#4 V");
      lcd.println( "volt");
      lcd.print("A");
      lcd.println( "amp");
      break;
      
    case 5:
      lcd.print("#5  ");           //spare
      lcd.print(" spare  ");

      break;
    case 6:
      lcd.print(" #6 spare 2");        //  spare 2

Which mess?

Hello tom321

We need some additional information.
Post your complete sketch, well formated, with well-tempered comments and in so called code tags "< code >" , a real schematic and a picture of the solderings of the LCD to see how we can help.

Have a nice day and enjoy coding in C++.

Do not use println(). The println function is not supported by any of the LiquidCrystal libraries.
