            FragmentTransaction transaction = fragment.getFragmentManager().beginTransaction();
            transaction.replace(R.id.container, fragment);

The Java break is used to switch statement. It breaks the current flow of the program at specified condition.

You miss to add break; .

DEMO STRUCTURE

 public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    Fragment fragment = null;
    switch (item.getItemId()) {
        case R.id.nav_home:
            fragment = FragmentMarker();
            loadFragment(fragment);
            break;

       case R.id.nav_bookmark:
            fragment = new FragmentBookmark();
            loadFragment(fragment);
            break;
          }
       .......

Try

        Fragment fragment;
        boolean valToReturn = false
        switch (item.getItemId()){
            case R.id.nav_home:
                fragment = new FragmentMarker();
                valToReturn = true;
                break;
            case R.id.nav_bookmark:
                fragment = new FragmentBookmark();
                valToReturn = true;
                break;
            case R.id.nav_blog:
                fragment = new FragmentBlog();
                valToReturn = true;
                break;
            case R.id.nav_notification:
                fragment = new FragmentNotification();
                valToReturn = true;
                break;
       }
       loadFragment(fragment);
       return valToReturn;
