Duplicated Course units have been deleted

I was working on a different version of the published iVow course and had used the Duplicate Course button to generate another version in which I was changing the unit content and video links.

It appears after the most recent update to Course Press that the units disappeared. When trying to duplicate course again the course description content is present but the units are not duplicated.

Please advise how I can duplicate the course with the units intact and what has occurred to make the ones I was working on disappear.

Thank you ,

Wade Jackson
