NFS UNBOUND DECAL BUG???

hey guys, for some reason when entering a race in NFS Unbound, some, if not most of the decals I made on my car (regardless of which car, ALL OF THEM HAVE THIS) are kinda turned into a darker-coloured version of whatever base paint my car has. any fixes? For reference, the first pic has my decals on one side looking normal, while the second pic has the decals of the same car on the other side looking all muddy.
