Car select in multiplayer.

Xbox one forza motorsport 7
When I load multiplayer whether I am the host or someone else is the host I cannot select Any car but what is highlighted . I can hit RB or LB to scroll the entire page but I cannot select individual left and right from car to car . I have uninstalled and re loaded the game 3 different occasion’s now . I also noticed there’s a chat log in the bottom right hand corner of my multiplayer screens . I find it to be a useless bit added to the game… The main reason I purchased this game was to race multiplayer with my friends . Is there any help for this or have I yet again bought a product that was not ready to be sold to us, the consumer, thus wait months later .
Thank you,
Tommy Himes.
