Yeah, you've got a tune problem with the bow. Since your b'heads are hitting low/right, simply move your rest up and left about 1/64" at a time (I'm defining WA Shooter's "small adjustments" for you) and keep it up until you've got your Sonics hitting with your field points. Actually, trying to move both centershot and height at the same time can drive you nuts. I'd move rest height first, to get the groups both hitting the same elevation, then adjust centershot to bring the groups together.

If you've got to move the rest height a whole lot - to where the centerline of the arrow shaft would be more than 1/8" above the center of the mounting hole - set the height back so the arrow is centered and move the nockset instead (down in your case). When you get the groups close to the same height, then adjust the rest. Only move the rest height for micro tuning.

If your nockset winds up below square, you'll need to adjust your tiller.
