Installed the Catchup Pack, But Still No Cars

So I picked up the Volume Six Dynamic Catchup Pack for Need for Speed Unbound and made sure it was installed—it shows up as installed on my PS5. But when I jump into the game, I still can’t find the Audi R8 or any of the other stuff that comes with the pack. Already checked for game updates, and everything’s fully up to date. One thing to add—I’m running the game from a Blu-ray disc, but I’m not really thinking that would be the issue here. Still figured I’d mention it, just in case that plays a part somehow. Would be awesome if you could help me figure out where the pack actually shows up in-game. Right now it’s like it’s just vanished into thin air. Thanks for sticking with this—really hoping it’s just something simple I’m missing.
