Bugs in content types

Hi,

I am using H5P on Drupal 7.95. I have tried different content types (Interactive Video, Image Hotspots) and when I try to save them I get this error message: "You must choose an H5P content type or upload an H5P file."
I have tried it in Chrome and Firefox, and the result has been the same.
I have seen that other people experienced this issue in the past, but I have not found a solution for it, that is why I raise it again.
Any idea on how to solve it?

Thank you,

Jes

All the "Check your solutions" buttons for H5P-tools like Drag n Drop appear to be missing (After the tool itself finishes, its just white like in the following picture).

Hello !

I noticed today that the apostrophes / single quotes in the titles of the chapters summary show weird HTML characters. Not a big deal at all (there is a workaround) but, as I know that this issue impacts several other content-types, I thought that I should point it out as well :

Cheers,
