Looking at your sample, I think Matthews need to bend it a bit more at the first bend after the centre post.
Here's my very old Manfrotto ART: 003 and Matthews post. The feet on the Manfrotto touch which makes it look a bit off but once unfolded the post is straight vertically.
Hey, isn't that the same Manfrotto stand you recommended the Matthews over in another post?

If it was a cheap item that wasn't worth shipping back I'd be happy to do some DIY repairs - I had to do that with a cheap nano clamp I bought last year. For $70, they can get it right the first time. If all else fails, that Manfrotto one still looks pretty good.
