Braking line dissapearing?

I got Forza 6 yesterday and I’m literally hooked. While Forza 5 discouraged me from being confined on the track, namely because of the lack of content and the physics where no cars could turn, Forza 6 will now make me go on both Horizon and the track. I tip my hat to you, Turn 10 - Forza Motorsport 6 is quite frankly amazing.

However, doing the championships with Saloons (Audi RS7), I noticed that 1) the Drivatars are EXTREMLY reckless, trying to ram you on every corner at a high speed like trolls; and that b) the braking line disappeared and there is no way to get it back.

Now, I know some of you will say: <<braking line? Learn how to brake yourself.>> But please note it is the only assist I depend on, and generally, I don’t even watch it. I tried everything, from going to the settings as well as the difficulty; still, nothing. Could someone help me?
