I have the Endurance Pack DLC and I drive in a league on a P2. Under the "league" I can see my Oreca: But I can see only the skinpack from the league. There is no way to see the official skinpack as you can see in the picture below I asked to two friends in my league, one is still using the old UI and the other the new UI. The one with the old UI can see both skinpak, the one with the new UI can see only the league skinpack. Maybe there are some other cars are affected by this bug.
