I have quite a bit of experience with this rest and its my rest of choice. Judging by the pictures, I think you have the rest mounted too high. I like to set them so that the block the prongs go in is just about level with the bottom of the shelf. Once you do that, loosen the screws that hold the prongs in the bottom of the block and slide them out a hair or so. This will get your arrows through the berger hole. Then set you nock point at 1/8 above square and go from there. Once I figured this out, I have yet to have any kind of contact issues with this rest. Very smooth and very quiet.
