From what you've posted, I think it's the buyers problem and not yours. You haven't highlighted the face angle. In the link Tario describes the face angle as "pretty much square", but that's only Tarios opinion, and if you scroll down further on the PRGR listing, it shows that the face angle is +1, which means its closed right? So some people will see it closed but some people will see it as pretty much square.
Well that's what I think anyway. Good luck.
