That's the correct length for the shorter screw, so it could be that the mount is countersunk too deeply, or that the threaded holes on the bottom of the sight aren't tapped deep enough.
I think the best thing is to call customer service at 1-800-426-0048 and they should be able to take care of getting you a replacement. Sorry about the trouble, but we will get it corrected ASAP.
