We are having an issue with at least one faculty where the calendar is showing phantom attendance entries from prior courses. When we go to the Attendance Activity of the course in question there is no entry for what is showing up in the calendar. I have also run the Reset Calendar option from the Admin area with no result.
I also tried changing the end date for the course with no success in identifying the culprit.
Any idea anyone how to clear old entries that no longer exist in the attendance module of a prior course.
