Course incomplete

I have a private course with lots of lessons, 114 according to Lingq, but no tall of them are visible. When I try to edit the course, I can see all of them, but can’t access them it seems.

It’s a private course (called “ULP” in my account, in case that’s important for admins): Anmelden - LingQ

On the Edit Course page, please re-assign a level to all lessons and then re-save the course. That should fix the problem.
