How to clear a text before a new text is placed in some spot

Hi
Well it seems to work but the text is strobing
this is what i have changed so far

[code]
//**************** PERMANENT INFO DISPLAY PROGRAM ****************

//tft.fillScreen(TFT_BLACK);
tft.fillRect(225, 108, 48, 23, TFT_BLACK); // стираем старое    x y width hight //(355, 117, 90, 23, TFT_BLACK)
tft.setTextColor(TFT_WHITE ); 
tft.setFreeFont(FF6);

//temp1= 56; // x coordinate
//tft.setTextColor(TFT_WHITE);   
//tft.setFreeFont(FF33);//21

//tft.fillRect(+70 , 265, 21, 3, TFT_BLACK); //erase the line for numbers 
//tft.fillRect(+150 , 265, 21, 3, TFT_BLACK);
//tft.fillRect(+230 , 265, 21, 3, TFT_BLACK);
//tft.fillRect(+310 , 265, 21, 3, TFT_BLACK);

//************************************************************

tft.setCursor(152, 150, 1);// 285, 139, 1 //152, 150, 1
tft.println("MODE");

//tft.setCursor(285, 106, 1); //292, 106, 1
//tft.println("RIT ");

tft.setCursor(152, 125, 1); 
tft.println("AUDIO");      // testing

//tft.setFreeFont(FF41);  // 21
//tft.setCursor(10, 182, 1);
//tft.println("VCC -          V");

tft.setFreeFont(FF26);//6

tft.drawRoundRect(140, 15, 334, 143, 5,TFT_BLUE); //x y width high radius color rectangle A 


}

void loop() {   // put your main code here, to run repeatedly:





audioSwitchState = digitalRead(audioSwitchPin);   // check the status of the switc
  
  if (audioSwitchState != prevaudioSwitchState)   // compare the switchState to its previous state
  {
    if (audioSwitchState == LOW)                  // If the switch is pressed, count the press
    {
      buttonPushCounter ++;  
      buttonPushCounter %= 4;

    }
