Iphone 8plus calendar issue

I just started getting all the invites to other's calendar to which I subscribe. I didn't change anything I can think of and would like to stop this. I'm only getting these invites (the actual invite to accept/decline) on my phone and not computer. I don't know if "events affect availability" is part of it but I've tried multiple times to turn that off but it turns itself back on. There are so many event notifications that aren't mine and it's driving me crazy. (I also turned off "invitations", "invitee responses" and "shared calender changes" in the customize notifications area for the calendar app). Ideas, what am I missing?
