Bugs in content types

Interactive videos inserted into Moodle course via H5P plugin do not have the video control bar at the bottom in final embedded video. Everything else works perfectly.

Moodle version and H5P plugins both current. Base video is MP4 H264

Video plays ok when started and interactions work perfectly. Just can't control the video or see how far through the video I am. Same applies in admin backend and as student.

have tried with three different videos - same on each. Non interactive MP4 videos look and play normally.

PLEASE: any clues on cause and fix?

One of the great benefits with using H5P is that it gives you access to lots of different interactive content types, such as presentation, interactive video, memory game, quiz, multiple choice, timeline, collage, hotspots, drag and drop, cloze test (fill in the blanks), personality quiz, accordion, flash cards, audio recorder.

In Moodle3.10 on desktop when adding interaction of text sometimes the text box is "folded" and all the space to write on disapears.
