We accidentally posted Workbook 3 grades to the Workbook 2 assignment in Canvas.
Fortunately, we caught this right away.
Workbook 3 grades should now be posted correctly.
We have re-posted your Workbook 2 grade (hopefully correctly).
The only issue is that if you look at your Workbook 2 grade comments you will see your workbook 3 grade comments (and extra copies of the workbook 2 grade comments).
