How to fix "ghost-mods" in vechicles menu

How to remove these empty boxes?
In these there're some not working configs. They're also not in mods folder.

 

Try going to vehicle config -> Save & load (I think it was there) -> Open user configurations folder, then backing up a folder. If you’re in a folder called vehicles, then that’s good. Try removing folders that share their names with these empty boxes. That should work. I think.
