Problems with mods: what happens when I spawn mod vehicles in 0.14.01!!!

How did this happen: I spawned about 5 mod vehicles based on Gavril grand marshal with "Replace current",
and their headlights, taillights, glass, pipes, and other parts from all cars i spawned was on the next car!

i bet you don't understand, so i placing a screenshot here

looks really terrifying, isn't it?

i placed 2 files under here, try to spawn these mods with "replace current"

if you're a developer of this game, fix it, PLEASE!!!

 

in 1.13 all worked well, but... yes, these mods have same names of the parts beacause they were based on default vehicle (and most part of other mods i downloaded too), and they're also a bit old.
