Units showing 0% even after completion

I have noticed that on certain units it will show 0% in the blue circle after I complete the unit in full. There are no mandatory questions in the units. However, some units do show 100% after completion.

I have tried turning Coursepress Pro On and off and I have updated to the most recent version. I also tried the course under a "student" account and not administrator, and it still shows 0% almost randomly on some of the units.

Thank you for your time,
Jenni
