Bugs in content types

Unless I made any mistakes in the settings (which I cannot rule out), there seem to be two issues with the "Drag and Drop" question type in the "Quiz (Question Set)" content:

1. It is only possible to drop the text areas, i.e. the answers, into the correct drop field, but not into the incorrect ones. This does, of course, make the quiz much easier than intended.

2. Despite this restriction, H5P still tells me the given answers are wrong when checking the results, which is contradictory and wrongly results in minus points.

I have been creating Vocabulary Quizzes within the LMS Canvas with the Flashcard content type and when the students open the quiz, they can't see the flashcards and can only see the "next" and "back" buttons and the content description. Does anyone know why this might be happening?

Love your help with this. 

Our developers are saying its a problem with the H5P plug in / video player. Just wondering if anyone else has experienced this problem or has any ideas of whats going wrong.
