If you damage the right hand side track the undamaged track is still displayed. My guess is that the functioning track animation remains when it should disappear because you see twice as many axles as when the track is undamaged. If you shoot the left hand side track first you see the animation of both left and right tracks being damaged at the same time. If you then look at the right hand side track the damage shows up as if that side were damaged, but in this case there is not the double axle/track bug.
I checked this out on the new Tiger I and all the animations and before and after renderings look as one would expect so I'm guessing this is just a Tiger II bug.
