West Cost USA drag strip speed and time not showing

I am trying to test my custom car configs on the west coast USA drag strip. But, most of the time the speed and time of my car are not showing on the digital board at the end of the drag strip. How to fix that problem? What am I doing wrong? Please help.

 

I'm also having the same kind of problem: lights don't work in order or don't work at all and time boards missing some number digits somstimes. Hope they will fix it soon..

 

For me, the drag race doesn't even end if I use a mod car for the opponent.
