CoursePress Pro Troubleshooting - Unable To Add Content To Units

Hi There:

I am having trouble adding content to the units in my courses that I have started to build using your CoursePress Pro plugin. I have created a video detailing the issue, which can be found here:

While I have done a search and have seen that others have had the same issue, it seems to me as though their posts are a bit older and perhaps another workaround has been found.

If you guys have any insight as to how to add units and make them stay in the course, that would be great.

Thanks,

Dan
