There are a few reasons why this might be happening.
Once you have excused, allowed a retry, or graded an item, you can hit the “Refresh List” icon and this should remove it from your list.
If students have submitted work prior to you hiding or deleting an assignment/assessment in the Editor mode, the item will likely remain on your list after you complete the steps above. In order to correct this, you will need to do the following:
- Un-hide the assignment.
- Grade the assignment again, while it’s visible.
- Re-hide the assignment. The grade will then be removed from the grade book.
* Please note that students may notice a brief change in calendar or grade during this process while the assignment is un-hidden.
