The answer is obvious, but often overlooked. You're shooting a bow that was set up for someone else, not you. You need to have the kisser button, and any other accessories set up for you. Then you need to tune the bow. The guy shooting it before you had a different style. Tune the bow for you, set it up for you, and I can all but guarantee you those sights fall down where they should be. If that doesn't work, there's another problem, and the likely candidate is in the sight installation itself.
