TBS Mikado's & Heavy 2-10-2's Texture Glitches

I am not sure if I'm the only one with this issue when using any of the mikado's or 2-10-2's by the back shops that when you look at the models a certian way, the whole model turns pitch black. The odd thing is this issue doesn't happen to any of there decapods, consilidations, or t85 4-6-2's. What was done differently on those models vs the mikado's and 2-10-2's and is there a fix to this issue????
