Can't delete instances of recurring all-day events
We have recurring all-day events. When we delete just one day, it either isn't removed or another day is removed.
For instance, the "test 1" event was created to run from Dec 23 to Jan 10 on weekdays. When I delete the Dec 24 event (that date only), it is removed from the calendar. When I refresh the calendar, the Dec 23 event has been removed and the Dec 24 event is back.
We get the same behaviour if we log out and log back in.
Any ideas?
