Bugs in content types

Hello All,

I am currently working through Pressbook, and have been trying to embed the example Flashcard H5P activity into my content. However, each time I try, I receive the error message:

Validating h5p package failed.

Missing required library H5P.Flashcards 1.5

I'm using a Google Chrome Browser right now on a Mac laptop if that matters. Any ideas? Also see attached image on the Pressbook admin page for more info. Thank you!!

I've inserted a video on the first slide in Course Presentation. The video is suppose to autoaplay but it won't start if it's on the first slide in Course Presentation. 

Moodle
Chrome Version 90.0.4430.85 on Mac OS 11.2.3.

In an activity I put the following as an answer

He’s a doctor.

then I attempted the activity and wrote

He's a doctor.

The answer was marked as wrong due to the apostrophe.

I am using a chrome on a chromebook which is updated frequently.
