Bugs in content types

I am just walking my first steps with H5P and I am really exhited about the possibilities. My first trial is a drag & drop question and I am just struggling about the number of results being showed at the end of the task. In my trial there are six draggables but the results never show more than five. You can try here - place 6 draggables in the dropzone and finally click "Überprüfen":

As I couldn't find any hint to this limitation anywhere in the documentation: where is my mistake?
Thank you!

We have been experieicng issues with the Flash card content type.

Detailed steps to replicate the issue:

1.) When an interactive video is part of a branching scenario and it is defined to be autoplayed after a specific branching question, the interactive video starts already when the question is displayed and not afterwards. It works, if you use youtube videos, but not when videos are stored locally.

2.) Drupal 7.67

3.) Desktop and Mobile

4.) Browser: all

5.) H5P plugin version: 7.x-1.43

6.) H5P Content Type is Branching Scenario (beta) (1.0.10)
