Score in interaktive video not transferred to moodle
I'm quite new here and didn't find any help, so I'll just ask.
I created an interaktiv video inside my moodle. (In fact, I created more than one.) I don't know, what went wrong, but all the marks in the timeline of the video appear blank. In other videos, I created, they are filled. Which is my first question - what is the difference between filled and not filled marks? (I uploaded two screenshots you can see below.)
Second: The video works fine, it stopps at the right time, the questions appear, they can be checked - but some students don't get the record written in their gradebook. Why?
Thanks for your help!
