Having to search for parts in menu? RLS

Evening,

Finally decided to sink some time into the game, last time i briefly tried it, when i wanted to modify a vehicle, i had to manually search through the menus to find each part.
After watching some videos on youtube, i ended up installing the rls mod, same thing as before though, whenever i try to modify a vehicle, i have to manually search each part. Is there some in game setting im missing that displays all parts? Every video ive seen, every customizable part is shown in the menu with no searching required
