Rick,
That does happen, generally because of excessive dip (or if you
prefer, after-touch). Set a proper dip so that the escapement will be
clearly completed (you can watch this), and see if you develop some
clearance between the jack and the underside of the hammer flange. (I
wouldn't try lowering the hammer line, unless it was clear that this
was out of range ...like, 1.5".)
Could be the rails are too close together.
