iPhone iOS 16.3 Calendar issue

Since the new update to iOS 16 my iPhone 12 Apple calendar is having two issues. One, the reoccurring scheduled events in the calendar show up as scheduled for multiple times a day, everyday of the week for the entire year. Secondly, if I try to schedule a new reoccurring event they don’t show on the calendar. However, I can find them in the calendar search. I’ve tried scheduling them using the custom option and no custom and it still isn’t showing. I’ve deleted the reoccurring events and started over but that didn’t help. I’ve rebooted my phone. That didn’t help. I went to setting and made sure the “all events” were turned on. Still not working. My calendar doesn’t sync to any other devices but just to make sure I’ve checked all the boxes I made sure my default calendar and the sync were correct. They’re still missing. Scheduling a reoccurring event is a ghost in my calendar or it’s rude and screams at me by listing it as scheduled for 15 times a day, everyday.
