Unable to delete files from WebDAV

Hi I’m hoping someone can help. I have infuse linked to a WebDAV account.

I have enabled file management in infuse, and if I try and delete a movie file within infuse it also delete the file from my WebDAV which is fine.

However if I attempt to delete a show/season with multiple episodes it disappears and reappears seconds later in infuse so I can’t delete it.

There are no error messages, the show simply reappears.

Is this a known error?
