Not sure if this is an IOS or OS X issue, but it certainly affects both my systems. This morning I added an item to my iPad (latest update) calendar. As I looked at the month view on iPad, I noticed a recurring item showing later this month that should not have been there. OK, so I made a mistake when posting, but then as I scrolled back to earlier months, I noticed that the Feb. & Jan. calendars were empty, except for the items my wife had shared. When I check to see what calendars to show, I see a huge list "from my mac" and a list from iCloud. I store my calendars in iCloud, not on my iMac. All the calendars from my mac are unchecked and the ones I need to see from iCloud are checked. When I look at my iMac, the calendars are only from iCloud and everything shows from all previous months. To confuse me even more, I added a few test entries to my calendar on iPad and after I press the +, I see the entry and then it disappears.
Any suggestion on how to get my calendars to play nicely on iMac and iPad?
