I recently got a Vixen dovetail shoe and noticed the fastener screw is not flush with the inner side wall. This is causing only part of the fastener screw tip to press against the rail as you can see in the photos below. Seems it would make it less secure and more easily damage the rail. I have two other dovetail shoes made by GSO and the screws are completely flush, so I'm wondering if this a manufacturing defect.

 

Should I contact Vixen to get a replacement shoe? Or is this common/intentional and I shouldn't be concerned with it?

Contact them, or add a spacer on the opposite side, which you shouldn't have to do.  In the meantime be careful if you use a spacer.

I'm just throwing this out here for some engineering opinions.  What about grinding a uniform bevel on the tip of the bolt that is about the same angle as the manufacturing error?  This would mean the center of the bolt would do the holding instead of a small part of the edge.

Judging from the number of gouged-up dovetail bars I've seen, I'd say it's pretty common 😉

I put a piece of UHMW tape on mine to let the screw tip "dig in" if it needs to.
