Can't delete Steam Input Configs

This program doesn't seem to detect any saved files on appid 241100. Everything else seems to work fine. How can I delete controller configs?

[GMMan]

I'm not sure config-type apps are supported. Perhaps they're stored as UGCs rather than cloud files?

Maybe that is the case, but they still take up space on Steam Cloud. Would it be possible to add support to delete or upload configs?

Any updates on this issue?

I could delete them once within SteamCloudFileManager, successfully or so it seemed, but they still persist when I check on Steam
