Calendar dots on every day, but no event
My wife's iPhone's (7 Plus, v.11.4.1) calendar, in month view, shows dots for every day, from July 27, 2018 through June 22, 2020. From list view, on July 27, there is a phantom event, titled New Event, with a start time of 10:00AM and end time of 10:00AM. This event does not show in day view; only in list view. Then, on July 28, 2018, this same New Event (same start/end times) shows twice in list view (not present in day view). Then, July 29, 2018, this same New Event (same start/end times) shows three times. This repeats itself until the same phantom event shows five times in list view every day; but not in day view. It continues to show the phantom 10 AM to 10 AM New Event five times, every day, through June 22, 2020.
I cannot delete the event. Attempting to do so crashes the calendar. Upon opening the calendar, the offending event remains. I cannot edit the event in any way (say, by changing something, like the title or end time) because clicking Done crashes the calendar. I've also tried adding a new, useless calendar so that I can move the phantom event to it and then uncheck View of that dummy calendar. Just trying to reassign the phantom event to the dummy calendar crashes the calendar.
I've tried rebooting the phone and editing. Same deal.
I'm thinking of restoring to factory defaults and then restoring from backup. But, wouldn't this just restore the problem?
Any ideas appreciated.
Thanks.
