Main window bugged

Hello,

I cannot select any other car than the Simco Clio 2016 and Oulton Park International.
I subscribed to some cars and tracks, for example the Indycar 2014 and Sebring but when I select a car in rFactor 2 main menu, nothing else appears, just the Clio and for the tracks, only Oulton Park.
Some days ago I could choose everything but now I have this bug. I haven't removed anything, I verified the game's integrity and reinstalled it but nothing changes.

Any idea?

 

From Main Menu click on Series, select "ALL Tracks and Cars" and click Accept

 

Thanks it is solved.
