An instructor was re-arranging some assignments in a Brightspace course. An Assignment that was linked to the grade book was removed as it was no longer needed. The Assignment, hwoever, was removed without un-linking it from the grade book. As a result, the corresponding column was left behind in the grade book, still has the association with the Assignment tool and cannot be deleted, at least, in any way that I can see. Is there some way to remove such a column from the grade book under this circumstance?
Thank you for your time!
