Bugs in content types

I seem to be experiencing a problem when adding subtitles to an interactive video, in the past I was sucessfully able to add english subtitles to a video but now when I am trying to add an additional track for lativian subtitles, the track name is selectable in the video but no actual subtitles appear. This also sometimes happens when adding a single subtitle track to an interactive video.

Detailed steps to reproduce the bug (exactly how and when did it happen)

Detailed steps to reproduce the bug (exactly how and when did it happen)

Hi 

I have a course presentation created directly at H5P.org. I wish to upload it to my H5P.com account. I have enabled the download button and display lower toolbar option. I only see Reuse or Embed. If I click reuse I can download an H5P file with the correct extension but when I upload this into H5P.com a number of required libraries are missing (course presentation, true/false, multichoice etc) and the upload fails. This is all done on a desktop. I have tried Chrome, Explore and Edge. 

In H5P presentations the full-screen button sometimes appears, sometimes it does not. This happens in the 'environment' and I can't find an explanation for it. There are no settings to enable/disable the full-screen button. I experimented with 2 presentations with the same content in the same environment (browser: Chrome on desktop), please see attached screenshot.

Any explanation, please?

Thanks and regards
