problem with Numidian cavalry and Roman helmets

I got some Numidian cavalry as a gift from the senate. The description says that the Numidians don't use saddles or bridles, just a stick to steer their horses with. Yet on mine when I look at them on the battlefield, their horses DO have both saddles AND bridles.

Also my Roman legionaires' helmets are wrong. The part in the back of the helmet that sticks out, it doesn't stick out far enough. It looks kinda bad after you see pictures of real Roman helmets that look cool. In the game the helmets look dumb. :(
