CreateMeetingBottomSheetAdapter.java:84 wäre timerSelectValues.set(0, View.VISIBLE); im Block

// preset pairs
presetPairs = database.countdownPresetWIthParentDao().getCountdowns();
presetPairs.forEach(preset ->{
    timerSelectValues.add(View.INVISIBLE);
});
timerSelectValues.set(0, View.VISIBLE);

App stürzt nicht ab, wenn vor Klick auf den + Button mindestens einmal das SettingsFragment aufgerufen wird.
