I just noticed that your deck has 98 images, so there are (at least) two cards that lack an image. Would it be possible to fix this?

I'm not seeing this. Just did an import of the deck to an empty Anki profile, and I seem to be getting 100 files in my collections.media/ and all the cards look fine in Anki.

I didn't figure out how to change the description of an existing deck, so I reuploaded it here: https://ankiweb.net/shared/info/1057359699 (I've removed my old shared one, please update the link)
