Thanks for the Gradebook History tip. I forgot that tool was there. So whatever did it happened on Jan 11 at 1:37 to 1:38 AM. I'm thinking that the easiest solution to get those zeroes out of the gradebook will be to just make a new quiz and delete the old one.
FWIW:
- Yes, it was imported, but all the dates were changed.
- The due date/available until dates have not passed. It's not even available to take yet.
- No one else has grading access (unless there's some Canvas hack none of us know about).
- Grader is listed as "Not Available" so it appears to be some automated thing.
I think what really confuses me is this: How could the system grade something for some, but not all, students before a course is even published? Maybe the unaffected students added after the 11th? But I'm lost on what triggered this in the first place.
I'll just create a new one and delete the old to solve the problem (before students freak out).
Thanks for the help,
Traci
