How to assign category to my shared decks?

I have shared several music related decks, but only one of them is listed in the “music” category. How do I assign a category to my shared decks?

Search for “AnkiJazz” to find the decks I’m talking about.

Thank you in advance.

I found out myself: when I shared my decks I added a comma-separated list of tags (“music, scales, modes”). When I leave out the commas (i.e. “music scales modes”), my decks appear in the music category.

Now I get the error “Sorry, you’ve reached your maximum deck shares this week.” although I deleted all my shared decks and wanted to re-share with correct tags. Looks like not a big deal, will do so next week.
