Removing incorrect birthday event from calendar when it doesn't appear in contacts
Hi
I have an incorrect birthdate showing up on my Apple Calendar that I can't delete or edit. What I mean is that on a particular day this person's birthday shows up as two events. On my calendar, it reads "XXX's 49th Birthday" and also "XXX's 50th birthday". The 50th is the correct one and the one that is connected to the birth date for that person in Contacts. When I click on the 49th birthday event and click "show in contacts", it takes me to that person's card in Contacts with the correct birth date. This is only happening on my Mac. On my iPhone calendar there is only the correct birthday event showing up.
I am not importing/subscribing to any calendar where the incorrect date could be imported from as far as I can tell (plus the second event should show up in my iPhone calendar too which it doesn't).
Any suggestions?
Thanks.
