Myself and a number of the other TAs are unable to mark units as Incomplete. When we look into the student's box, under the Education tab, the only options are "Grading" and "Mark as Complete", although the unit is already complete. Some other TAs are having the opposite issue in which they only see the "Mark as Incomplete" option, even though the unit is not complete.
The behaviour of this bug seems unpredictable. Please assist.
