Movie Leader Prime Question???

Anyone encountered stress marks on their Leader Prime's kneepads?
Its on the red plastic on the 2nd layer of the kneepad where there are 2 metal rod inserted, the part that connects to the grey plastic. The area where the upper metal rod is ( The part that allows you to flip that part ), seems to have stress marks on both side of my Prime kneepads.
I would take a photo of it, but the resolution isn't visible enuff.
