When "Bis am" selected the 1 in "for ____ times" is still looking like it's selceted. Maybe this could be a lighter grey or no number at all, so that it is clear that this option is not selectedInstead of the 1 it should be "Auswahl".
Steps to reproduce:
1. Clcik to create an event.
2. Go to recurrence.
3. Select " am".
When selecting "am" you can get confused because there is a black 1 in the space after "for".
It says "Auswahl" instead of 1 so you know that you haven't selected that option.
