When I attempt, usually after the question is originally created, the quiz will propagate duplicate copies of answers. So that in the original question will have 4 answer choices. When the next time the question is updated, it will have 2 sets of 4 answer choice. In that choice of 8 items, one set will be a duplicate. Then if I try to fix it by deleting 4 choices, the question will save sometimes with 16 answer choices! Great quiz question option, but frustrating to amend questions. Probably a coding error?
