Local menu problem

I Have an issue where for the first time after a reset when I press the up arrow panel button which I have assigned an interupt it is supposed to display the main menu but actually displays the second menu. I have to press back menu option to get to the main menu. Once I do this after startup it works as it should. Maybe someone can see the problem.

The readbuttons function is exactly the same as the demo

Any ideas are appreciated.

Here I assign the interupts

  attachInterrupt(25, upPress, FALLING);
  attachInterrupt(24, enterPress, FALLING);

Here is the upPress function. As you can see I am trying to reset all of the menu option to defaults.

void upPress()
{
  if (runMode)
  {
    //    SerialUSB.println("runMode to 0");
    MenuLevel = 0; //menu tree depth -> second level
    MenuID = 10; //unique menu id -> has to be unique for each menu on the same menu level.
    buttonUpState = 0;
    prevBtnUp = 0;
    lastBtnUp = 0;
    enterPressed = 0;
    buttonEnterState = 0;
    prevBtnEnt = 0;
    lastBtnEnt = 0;
    backLightDimmed = 0;
    analogWrite(backlightPin, (map(5, 5, 0, 255, 0)));
    glBackLightDelayTime = millis();
    lRunModeTimeout = millis();
    MenuMain();
    runMode = 0;
  }
}

The enterPress function.

void enterPress()
{
  if (runMode)
  {
    backLightDimmed = 0;
    analogWrite(backlightPin, (map(5, 5, 0, 255, 0)));
    glBackLightDelayTime = millis();
  }
}

The loop.

void loop()
{
  if (runMode)
  {

    //    if (bAuthenticated)
    //    {
    //      if ((millis() - lLogintimeOut) > 10000)
    //      {
    //        bAuthenticated = false;
    //        loggedIn = 0;
    ////        currPage = 1;
    //      }
    //    }
    
    listenForEthernetClients();

    if ((millis() - lSpLoop) > 5000 && sMode > 0)
    {
      lSpLoop = millis();
      occProcess();
      outputProcess();
      monitorProcess();
      outputProcessPrint();
    }

    if ((millis() - glBackLightDelayTime) > 30000 && backLightDimmed == 0)
    {
      //isLocked = true;
      backLightDimmed = 1;
      analogWrite(backlightPin, (map(0, 5, 0, 255, 0)));
    }
  }
  else // use local menu buttons
  {
    ReadButtons(); //check buttons
    Navigate(); //update menus and perform actions

    if ((millis() - lRunModeTimeout) > 30000)
    {
      setRunMode();
    }
  }
}

Here are the menus.
This is the menu I want on the first press of the up arrow.

void MenuMain()
{
  //menu inintialisers
  channel = 0; //starting row position of the cursor (top row) - controlled by the button panel counter
  channelUpLimit = 6; //upper row limit
  channelLowLimit = 0;
  MenuLevel = 0; //menu tree depth -> second level
  MenuID = 10; //unique menu id -> has to be unique for each menu on the same menu level.
  enterPressed = 0; //clears any possible accidental "Enter" presses that could have been caried over from the previous menu
  lcd.clear(); //clear the screen
  //actual user content on the screen
  lcd.setCursor(6, 0); //set the cursor to the sixth pixel from the left edge, first row.
  lcd.print("Main Opt"); //print text on screen
  lcd.setCursor(6, 1); //set the cursor to the sixth pixel from the left edge, first row.
  lcd.print("Temperature Opt"); //print text on screen
  lcd.setCursor(6, 2); //set the cursor to the sixth pixel from the left edge, first row.
  lcd.print("Voltage Opt"); //print text on screen
  lcd.setCursor(6, 3); //set the cursor to the sixth pixel from the left edge, first row.
  lcd.print("Percent Opt"); //print text on screen
  lcd.setCursor(6, 4); //set the cursor to the sixth pixel from the left edge, third row.
  lcd.print("Save Settings"); //print text on screen
  lcd.setCursor(6, 5); //set the cursor to the sixth pixel from the left edge, second row.
  lcd.print("Run Program"); //print text on screen
  lcd.setCursor(6, 6);
  lcd.print("About");
  ScrollCursor(); //enable the moving cursor (note that this function is not called in the splash screen, thus disabling the cursor)
}

This is the menu that I get on the first press of the up arrow.

void MenuSetupPg1()
{
  channel = 0;
  channelUpLimit = 3;
  channelLowLimit = 0;
  MenuID = 11;
  MenuLevel = 1;
  enterPressed = 0;
  lcd.clear();
  lcd.setCursor(6, 0);
  lcd.print("Mode(0,1,2");
  lcd.setCursor(80, 0);
  lcd.print(sMode, 1);
  lcd.setCursor(6, 1);
  lcd.print("Occ Mode(0,1");
  lcd.setCursor(80, 1);
  lcd.print(sModeOcc, 1);
  lcd.setCursor(6, 2);
  lcd.print("Reset");
  lcd.setCursor(6, 3);
  lcd.print("Back");
  ScrollCursor();
}

Here is the navigate function.

  if (runMode == 0)
  {
    if (valueEditing != 1)
    {

      if (MenuLevel == 0)
