When I link a Mastering (physics) assignment to Canvas it creates TWO grade columns.
I have the Mastering assignment ready to go. I create an assignment in Canvas and choose the submission type to be External Tool and select Mastering Assignments. It all seems to work until the assignment is due and needs to sync with Canvas. For some reason two grade columns are being generated in Canvas and Canvas is "grading" or syncing with a column that has no information from Mastering. I must delete that grade column and then re-sync for the grades from Mastering to populate in Canvas.
How do I stop this from happening?
