Hi, I get your same problem randomly... my solution is to open another page in the app (current standings, for example) then hit the "BACK" button (top right on your screenshot)... when it reloads the car selection page, everything works as it is supposed, everytime so far... I just did it to join the 17.00 MKMotorsport, had the exact same page you posted...

Thank you very much, that worked perfectly!
