first tab does not always respond to click with onTabSelected

[AlaaZarifa]

I can't understand what's happening here, basically the first case (tab) isn't triggered most of the time, by that I mean, it will guaranteed to work when I click on the other two tabs/cases !!?? I know it's ridiculous, but when the click on Email tab then on Home it will be triggered and it will replace the fragment normally.!?

I issue doesn't happen to the other two tabs.. just the first "home"..! the IDs is accurate btw.!

any help here?

 @Override
  public void onTabSelected(@IdRes int tabId) {

    switch (tabId) {
      case R.id.navigation_home:
        HomeFragment homeFrag = new HomeFragment();
        FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
        fragmentTransaction.replace(R.id.Container, homeFrag);
        fragmentTransaction.commit();
        break;

      case R.id.navigation_email:
        sendEmail(API_EndPoints.email);
        break;

      case R.id.navigation_phone:
        dialContactPhone(API_EndPoints.phone);
        break;
    }
  }
