Wallpapers not showing up

I’ve created the .local/share/wallpapers folder and added my own day/night folders, but they’re not showing up at all when I go to select them. I didn’t have any issues with this on workstation kde plasma, just immutable kinoite. Using the same folders, metadata.json file and everything that worked on workstation, can someone help me out? I’m assuming there’s some difference between standard and immutable that I’m not understanding.

I’ve checked, if I put a single .jpg or .png file in the folder, it shows up, but the directories don’t.

Same folder for me, but I just use subfolders and PNG files. Everything shows up

The folders that use metadata.json are usual /home/user/.local/share/plasma/desktoptheme and /home/user/.local/share/plasma/look-and-feel
