Windows are completely white, so it seems as a sort of temp skin. Not sure, but it's not working correctly indeed.
Your own skin does look correctly when you look at the replay?
Do you get any fault notifications when loading the track?
If you remove the newly made skins, do the default skins work correctly again?
If you make just 1 new skin, and put that in the game, do the other drivers have normal default skins again?
