Bugs in content types

Running Course Presentation using Drupal 7 on both Chrome and Safari on both Mac and iPhone, just uploaded H5P a few days ago.  When I insert an interactive video and leave Auto-play unchecked, it behaves as it is supposed to.  If I select Auto-play, it begins playing (I hear the audio, at least) sometimes when I open the presentation and, if not then, everytime I select the slide before the slide containing the video. If I insert the video using the non-interactive menu item, it will Auto-play correctly. Any ideas?

Thanks

The following content types have issues:
