Good afternoon,

Our first day of class began today, and we're having some strange bugs popping up. The latest one is something I can't seem to solve.

A faculty member has some quizzes in their course, which are already published. Bizarrely, 2 of them have already dolled out a score of zeroes to these students, despite the due date not being listed until September (he does have the automatically give a zero if turned in after deadline). It's not for every student, either.

Any suggestions on how to go about figuring out this issue? Thank you very much
