You would need to mod the track yourself to fix it.
I remember reading on the studio 397 forums that the guy was looking at it, but nothing have happened.
Though, I also seem to remember someone doing an unofficial, non-steam workshop release with some fixes. Might be worth checking that out (but that would mean you and the ones in the league would need to manually DL and install it).
EDIT: Sorry, didn't realized that there had been a new Bahrain released. Then only my first line applies.
