That's an original gp4 car. Templates are mapped to certain shapes, so the template you painted would have come with the carshape it was meant for. You can't just put any texture on any car, each template is made specifically for the shape it is meant to be used with. That's why is is appearing weirdly in game, as your putting your texture on an original carshape. You need to put the carshape that was with the template in the slot you want and make sure you have the textures named correctly.
