Bugs in content types

1. Detailed steps to reproduce the bug (exactly how and when did it happen)
   I created a new H5P (Agamotto, but the bug exists for other types too) in the Content bank in Moodle 3.9 and tried to add an image. I get an "Invalid Security Token" error and the image isnt uploaded. I can upload the same image to 'old-style' H5p content in the same course, and to e.g. Moodle books, ATTO, etc
   
   
2. Platform and version number. E.g. Drupal, Wordpress, Moodle.
   Moodle 3.9
   
   
3. Mobile or Desktop

Hello, folks,

I created interactive presentation which contains 20 video's and has tests (multiple answers/single answer type) after each video. When user answers to all questions and submits results it should save results in the gradebook (if I understand it correct). But after refreshing the page all results dissapear and user needs to answer it again. Also there are no grades in gradebook (after user finishes Presentation). Maybe some of you faced this issue or know how to solve it?
