Car Addons with Mods problem

So I am trying to add a Jeep into my server and when I load in the server I get this

but when I restart the car resource I am able to see the mods and modify the vehicle, but when I leave the server and join back I have to restart the car resource again for them to work again.

And this is with the mods on the vehicle
