I finally got my string shot in and I'm starting to hear a clicking noise after I get to full draw. Doesn't happen everytime, maybe 1 out of 10 shots. It sounds like its coming from the upper half of the bow but I can't pinpoint it. I've checked every little thing on the bow but can't figure what it is

I did notice that since the string is shot in I have 3 tuning dots showing on the top and 4 showing on the bottom. Anyone have any ideas on what I should do? Thanks!
