Is anyone else noticing on some of the Russian guns the zeroing always keeps defaulting to 440m?

Is there a way I can turn this off or maybe I'm making a mistake of my own? It never seems to happen with Western guns, but specifically AKs I'm noticing this with.

Edit: I figured out the problem, guys. I was running a grenade launcher and probably was adjusting the zeroing by accident with the intentions of switching to the UGL. It's a rookie mistake, but one to watch out for.

Thanks again
