Make sure the rest is hitting its full upright position either right at full draw or an inch or so before. You dont want it hitting any sooner than that or it wont drop fast enough. If your good on that then you can either turn your nock just a smig conter clockwise to keep that right fletch from hitting or you can slide the rest closer towards the riser which will allow it to drop a little sooner, but if you do that then you have to adjust your timing cord. Hope this helps, good luck.
