Visual issue on Aethertech character

[TlTAN]

Hi, i got and plastic surgery tickey on my Aethertech and i wanted to make him taller than before, the thing is that now when it calls the mech, there is always a part of the body that sticks out of the robot which makes it look horribly wrong, I will add some image to show that error.

Now it happens all the time with every mech skin i use, no matter what transformation i'm using, there is any part that appears on the mech.

On the picture the blue thing below the robot is part of the skirt of a transformation, it always look horribly wrong on my character, hope you can do anything about it.

Thanks
