Car pass not working

Hello. I have recetly bought Ultimate extension to forza horizon 4. Everything is working normally, DLC-s lego and fortune island are working too. But I cant claim any car pass cars. When I open DLC cars, it says to all of them “purchased”. When I click any of them, I can buy them for in game credits. But not for 0 credits

have you already claimed them once
you only get them free once
are you trying to claim them from within the autoshow …not the marketplace
