I have a Matthews Feathermax and performing the paper tune in my backyard I have consistently had the fletching marked left of the penetration. I tried adjusting the rest, that didn't work, so I adjusted it back. I released tension on the arms, that didn't work either. I tightened the tension, that didn't work. I'm at a complete loss, can someone steer me in the right direction here?

I know my arrows are the correct length for my bow so I don't know what the problem seems to be. Any advice would be greatly appreciated.
