Macbook Pro- iCcal events won't move or delete, reappear or move back
Frequently, but not at all times, when I change the day/time of an event, (recurring or one time), the event moves back to the original day/date/time. Drag/drop or open and edit both fail. Even deleting some events. They move or delete and then pop back up.
This is not new to this OS version.
