Why isnt other cars respawning?

I also use a kit or something for a yt named DutchDeveloper.. In his kit its also a auto car respawn thing.. BUT when i use other car and put it into the auto respawn model it dont respawn.. Anyone know why?

Check if the cars are the same name, if they are rename them and change all references of the old name to the new one, mostly because roblox lua gets confused when there parts that are named the same thing.
