In game CR required for dlc cars

I recently downloaded the car pass in order to access all the current FH2 DLC and from my experience of the launch pack etc I know that the first one of each DLC car you buy is free, but for some reason I am being charged for these cars despite not currently owning them? It doesn’t bother me too much as I’ve got money to burn on the game really but just wondered if anyone could shed some light on the matter?

Thanks

Have you tried a complete console shutdown? Sometimes, intermittent issues like these can be resolved by clearing the console’s temporary memory cache. Hold the Xbox One’s power button (not the controller’s) until the console turns off completely. Then, reboot, restart Forza Horizon 2 and attempt redeem your free DLC vehicles.

Tried the above method and still no joy. :-/
