If i will start a 100% non-championship race, it is 99 laps with a track of 6 km lenght!

First I changed the number of laps with the track editor. One time in the track information, one time in the pitstop stragegy. doesnt work. then I changed them with gp2edit. Same thing.
then i found this: viewtopic.php?f=2&t=266&p=3472&hilit=nu ... laps#p3472
And there it works, but only in the non-championship race! If i load my started championship its again 49 laps to do!!

Somebody may can help me?
