HYK US Units bugs

[SafetyCatch]

Hey guys

As some of you may know I've made some US Marines in Digi MARPAT based on Hyks US units.
However I've discovered an annoying bug with it and that is that all the units have triangular biceps!  
It's an ugly bug and one I would prefer to get rid of for future releases. Can anyone tell me why this happens - I think it's a selection problem.  

Cheers

was the model converted from odol to mlod?

Yes, but Hyks ODOLs had this problem too!

it's certainly a problem of selections. although i never noticed hyakushiki's units having this problem
anyway... i don't know exactly what you mean by trianglular biceps- so could you give me a pic of it, please.
