CoursePress hangs on Edit Course page with save Draft on each step

May be a mistaken post, I'm not using the Pro version...
I am trying out CoursePress on a subsite in a MultiSite I use for testing out plugins http://toni-esl.com/sitetest/.

I am trying to create a course on the Edit Course page in settings.
Each time I complete a step and hit "Draft" the page reloads okay, but there is a spinning icon next to the Draft button. It hangs. I have to manually reload the page, then I go continue to the next step.

Am I doing something wrong?
