I am experiencing a strange behavior with the SpeedGrader. I have a discussion assignment that is NOT a group assignment. However, when I go to the SpeedGrader from the assignment, I get the following message:

The group "[group name]" was automatically selected because no group was previously chosen. You can change the selected group in the Gradebook."

This only allows me to use the SpeedGrader for a limited number of students in the group that was auto-selected by Canvas. However, this is NOT a group assignment, so it shouldn't do this. Also, I haven't found a way to select a group (or unselect groups) from within the Gradebook as the notification suggests I can.

I'm lost where to turn here to fix this. Of course, I can still grade all the students manually, but I need to fix this bug for future assignments. Does anyone know why this is happening or how I might be able to fix it?
