As to your folders being re-created, I found this when
searching:
edit ~/.config/user-dirs.dirs
don't know if this helps, I've never had this.

Okay, its come down to that it's Trinity that's causing this issue.
I just purged LXQT from my system and rebooted and edited that file again,
saved it, and then logged out and back in and the file repopulated itself.
