The bit you are referring to is not a combination bit like the one that was used. The have added a string to normal bits and although there are a couple of mylar bits, the nose band is too narrow or is the old rawhide which is not allowed.
Unfortunately, it sounds like this is a personal issue for the steward and it needs to be addressed.
All this certainly brings to light some rule ambuitgy that should be rectified. Particularly when folks have been using that bit at the fei level, as well as at this event, with no issue. Three other stewards deemed the bit legal. There was only 1 who had issue. This should never have happened and highlighted areas that need improvement in the processes.
Combination bits are allowd in Jumping and Cross country with exceptions.

The leangth of the shank.
