In the old UI I had added the Porsche Manthey skins (Gelco) to the Porsche 991 GTE mod and to the Global Endurance Mod in the GTE Pro pack. However, with the new UI it automatically reverted to the original skins. Anyway to avoid this? I suppose, but I may be wrong, it is because the Manthey skin is mean for the GT3 mod and not for the GTE. Could that be the reason?
