Hooktheory doesn't show some scale charts and what seems to be audio which isn't possible to play

I’m not sure what is causing it and why it doesn’t happen to all charts, because some i can still see, it’s mostly the ones with audio below it that don’t work.
I wanted to include a picture of it, but it seems like new users can’t upload pictures in this forum.
Some help would be appreciated.

What section of the website are you referring to? Can you send me a link to a page that is doing this?
