What is this? (Genesis, Poser)

Upirium

So with this particular figure it has this weird line...

 

It looks like it's his hip lines but the lines don't go with it.

It onyl happens on this specific saved character for some reason the lines on the 'hip' don't follow him like the rest of my males?

I mean the grey part on the left male not the red part of the outlined leg on the right male.
