Bugs in content types

When I create the audio recorder content, nothing displays on publish or in the Wordpress window.  Does this content still work?

Hi, as said in the subject,

I like the feature Documentation Tool a lot. But unluckily, as soon as I press the button Submit on the Export Document Page, it doesn't submit anything.

P/s: also I would like to ask if there is any way to fix Save Content State since Save Content State doesn't seem to work too.

Step the reproduce the bug,

1, Add activity, choose H5P.

2, Content type: Documentation Tool

3, Add an export document page and 1 extra page for information

4, Try to input some text and go to export document page

  Good Morning l have a problem with H5p Video using Moodle.

When i put mathematical expressions into single-choice and multiple-choice questions, through the Latex code the expressions get too large and visually ugly, I would like to know how to fix this, attached follows two pics of what is happening.

Thank you.
