Video Description not shown

Good evening,

I wanna add a video course on a website via a YouTube playlist. You’ll be able to select each video separately and I want to show the corresponding video description. I already activated the option in the settings but the descriptions are not shown for any of the layouts (list, grid, mix).
I set up the page a couple of weeks ago for a demo for my supervisor and, if I remember correctly, the descriptions were shown then and I don’t remember changing anything since then. Do you have any idea what the problem could be?

Thanks and best regards
Dennis
