I've had four of our instructors contact us in the past 2 days with the same issue. I wondered if maybe they imported the content into a published course, and that's why it was happening, so I did some testing.
I have a FA23 course that's set up to automatically give zeros if assignments are missing. I imported that content into an Unpublished course, and some of the items were automatically given zeros.
I read the page on applying a missing submission policy, and it says it won't apply to unpublished assignments, but doesn't mention anything about an unpublished course. When you're importing from a previous course, all of those assignments/etc are published, and you can't unpublish anything that has student submissions, so it's not even possible to unpublish them. And, as others here have mentioned, we've never seen this issue in the past, so it seems like something new.
For anyone that has had this happen, the easy way to get back the dashes back in the gradebook (no grade) are to:
- Go to "Grades" in the course.
- Hover over the title of an item with zeros and click the 3-dots icon.
- Click on "Set Default Grade."
- Leave the box empty, but check the box to "Overwrite already-entered grades." (Obviously, don't do this if you have entered any scores yourself).
- Click the "Set Default Grade" button.
That seems to get rid of the zero and change the grades back to a dash.
