Remove "calendar administrator"
I somehow ended up with five entries (two different types ... ?) for my birthday in the Calendar on my 2019 iMac (Sonoma 14.1.1), so I wanted to remove the repeats, but it tells me I cannot because only the Calendar Administrator can do it. This is MY computer — I have no other administrator. How do I address this? I see someone else asked the same question four years ago, and it was left unresolved.
