Can't get any percussion tags to work

[jordanmholloway]

I've been trying to tag an upload for pierrot + vibraphone, and I preview the page each time I add an instrument, but for some reason 'vib' makes all of the genre categories disappear from the top of the page, so the only category is 'Pieces". I also tried it with 'perc' and 'mar' just to see what it would do. Same result. The tags that appear at the bottom are also not correct:

Scores | Holloway, Jordan Murray | Modern style | Modern | Unknown tag | Tag 'fl cl vib vn vc pf' | PiecesWorks first published in 2024 | Works first published in the 21st century

Here's the page in question: https://imslp.org/wiki/Shadyside_Loops% ... an_Murray)

Thanks very much for any help!
