Can't delete "Default'' folders

The issue you are facing:

I have a simple Nextcloud instance running via Docker on UnRaid. I want to use nextcloud to sync the contents of the “Documents/Videos/Pictures/Downloads” folders of my windows machines. I created a “Documents” folder on nextcloud to give each windows machine a target to sync the folder to. Upon creating the folder it was immediately populated with 3 subfolders:

My Music
My Pictures
My Videos

If I try to delete them they are immediately recreated. It might be an app I installed but I don’t see anything that looks like it would be doing that. There are quite a few apps so I’d rather not go down the list disabling literally every app one by one if there’s another way to figure out why this is happening.

Thanks in advance!

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Have a folder titled specifically “Documents” (Doesn’t happen if it’s just “Document”)
  2. My Pictures/My Videos/My Music subfolders will be created automatically and re-created on deletion

The output of your Nextcloud log in Admin > Logging:

No log events when said folders are deleted or recreated.
