When using Rubrics Enhancements, I noticed that the the button to "To duplicate a criterion from the rubric, click the criterion Duplicate icon [5]." Doesn't work properly. It seems to only let a user duplicate once. If you try to duplicate a duplicate, it doesn't seem to work either - it merely edits the current criteria. If you try to duplicate another it will just edit the original criterion that you duplicated. This doesn't seem like expected behavior.
