NFS Payback Wraps Disappearing

I have custom wraps on the ten vehicles I have and three of those cars have no issues but for the other seven, every time I load my game their wraps dissappear and don't reappear until I select each car to edit in the garage, then the wrap on the car I pick to edit reappears for the rest of the game until I start the game up again. As well as that, my wraps never appear on these seven cars in multiplayer. I've changed wraps multiple times and no luck. It's not fundamental but it's a very distracting bug and I'd appreciate any assistance.
