I don't know what I did, but somehow I deployed some assignments twice. Now duplicate columns are showing up in my grade book and I can't delete them. Students overall average is affected. How do I delete them?

I have had a similar problem when I export and import a course in Blackboard. I have extra columns that I cannot delete. However, it does not impact my students' grades since the columns do not contain any data. I have needed technical support to delete the columns in Blackboard.
