Duplicate Course Button Doesn't copy units with Course

I am having an interesting problem. I am trying to duplicate my course using the Duplicate Course Link, but when it copies the units pages are not in the copy. The only items that copy is the course and its settings.

Here is the URL that the link sends me to to duplicate the course:
