Hello Kip, I've been told the same thing, The arrow contact should be directly above the low point of the handle. I put a toothpick under the bear hair shelf so there is minimal contact with the shelf and it is contacting in the right place. It sounds like your nock may be to high pushing the arrow contact with the shelf foward. I'm not an expert though, this is just what I've been taught, hopefully one of the experts will chime in.
