Help!

I am trying to use my Bitzenberg fletch jig and I am not getting good contact between the clamp and arrow. Every time I use the thing the back part of the vane is dead center on the arrow, but the front tip of the vane is turned (curled) off from center and doesn't get good contact.

I like the jig, but I don't like the clamp contact. Any help from other Bitz owners, please!

PS - I have both a Right Helical Clamp and Staight clamp with both doing the same thing.
