I was in Preview mode on a quiz and clicked 'Submit" to print a copy of the test with the answers. Now I can't unpublish the quiz because there is a 'submission'. Is there anyway to delete that submission so that I can unpublish the test. Because the submission was from a teacher, it isn't showing up in Grades or SpeedGrader to alter it. I have it locked for now, but that isn't a good solution right now.
