One instructor is having this issue (see screenshot). Grades show only the students' names down the side and the assignment names across the top but the grades table/grid is not populating.

When I view the course, I can see everything. When I impersonate the instructor, I see what is in the screenshot. When I impersonate the other instructor who is in the course, I see everything.

I don't think this is a computer or browser issue since I am having two different experiences, one as myself and one impersonating the instructor, within the same browser on the same computer.

Does anyone have any potential solutions?

TIA
