Quiz (Question Set)

I'm experience problems with the Quiz (Question set). The editor works fine, but when I try to display the quiz it shows a few seconds and then it disapears. It seems not to be a conflict with another plugin, since I've tried after deactivating all the others (except h5p), but Quiz Question set still didn't work. I'm running h5p on Wordpress 6.7 and the problem seems to appeared after the recent update of the Wordpress-plattform. I'm using h5p 15.0, but I've also tried h5p 16.0 on another website and Quiz (Question set) doesn't work there either.

Clicking on the navigation arrows are making the whole page "jump" when the top edge of the H5P iframe is covered by the address bar of the browser, for example when scrolled down.

It has the whole page to jump way down. Its happening on wordppress as well as in the examples here: https://h5p.org/question-set

Just scroll down until the top edge is covered and then click on the arrow buttons. What could cause this behaviour? It seems to be related to anchor links on the buttons. 

Hi. Is there a way to change this setting when creating a question set? If I know that I do NOT want the answers to be randomized, it would be helpful for me to configure this. (use cases: questions have "all of the above" as an option, or "answers A are correct", or there is intention in the order of answer options: increasing length, years, etc.)
