For my uploads on 2026-04-05 and 2026-04-06 (see [[ https://commons.wikimedia.org/wiki/Special:ListFiles/Grand-Duc | Special:ListFiles/Grand-Duc ]]) that I processed using the Upload wizard, all files ended up with [[ https://commons.wikimedia.org/wiki/Template:Uncategorized{F75190280} | {{Uncategorized}} ]], despite me having added some categories in the wizard dialogue. I made sure to add "Category:UploadWizard" for the last example at [[:File:2026-04-06 Assistent zum Hochladen von Dateien mehrere Dateien – Wikimedia Commons.png]], but it still ended up without any category: https://phabricator.wikimedia.org/F75190280. I had to [[ https://commons.wikimedia.org/wiki/Special:Diff/1192821208/1192821318?title=File:2026-04-06_Assistent_zum_Hochladen_von_Dateien_mehrere_Dateien_%E2%80%93_Wikimedia_Commons.png | add it ]] manually afterwards.<br />
The same holds true for my uploads yesterday (and for the hedgehog today). I added the scientific names of the organisms depicted, but to no avail.<br />
Is that worth a bug report? I feel some urgency here, as ''Uncategorized'' maintenance categories are ballooning anyway, and needlessly adding workload doesn't sit right with me.
