Time Trial lap not getting onto the leaderboard

When driving TT and you set a new fastest lap, the delta-time is dissapearing and also the time is not saved. 

Need to restart the TT to get the delta back on screen. Not only on Hud, but also on the steering wheel.

Any fix? I am online, I can start a lobby and join others. Also I can see the times of my friends and the leaderboard. Only a complete restart of the game is helping, but the time is still not saved.
