All contacts birthdays appear in calendar at same date.


Jun 3, 2022
I have a Xiaomi phone. I see all of my contacts birthdays appear in google calendar at same date. I have not filled all these contacts birthday data myself. I also see same birthdays at same date next year and so one.

I checked calendar on my PC and I do not see all these contacts birthdays there. I believe this is some sort of bug. The contact list is quite large so as number of birthdays. How can I remove all these wrong birthdays from calendar on my phone?
