I have upgraded from OpenELEC, I have also tried to reinstall LibreELEC over but the settings submenu remains the openelec's one. is there a way to force a skin re-installation (without having to to a clean re-install)?
If it also happens with a new installation and the standard skin (depending on the LE version you use it´s either Confluence or Estuary then), could you please make a screenshot and get us a debug log:
