Bugs in content types

Hi,

I was trying to publish an interactive video with different formats available. I used 4 different resolution in mp4, and 3 different webm created from converting the same original mp4 with different converters. They are all uploaded in the streaming repository in moodle so links have been successfully pasted and saved in the h5p "add a video" tab as in pict1. When I save and try to play it only the 4 mp4 are available options (pict2). 

Wordpress version 5.3.2
H5P plugin Version 1.15.0

I have an interactive video. I would like to link to another content I created.

The URL I want to link to is 

https://mywebsite.com/wp-admin/admin-ajax.php?action=h5p_embed&id=3

However when resolving the URL H5P ist changing the & character to &

Hello,

Three bugs I've stumped upon in Essay activity :

1. In "Help text" hint, apostrophes and quotations marks can't be used : their html translations appear "&..." instead of these special characters ;
2. In solution, line breaks don't work ;
3. In keywords fields (used to assess the students' work with words and expressions), apostrophes and quotations marks prevent the recognition of the keywords using them (likely because apostrophes and quotations marks are used in code for text strings ?).

Keep good working,
