App refuses to set ovulation date correctly

Ju

My ovulation happened 15 days later than expected.

I have logged pictures of the positive ovulation tests, but the calendar shows me a very different ovulation date.

Also, the calendar predicts my period on 8. March when I know it will be 13. March due to the late ovulation.

Why can’t I change any of this manually anymore? In a normal cycle, I can easily adapt expected period days.

Thanks!
