Sounds like you have 2 issues....
#1) Adjust sight (Move to the right in small increments) for field points to be on target
#2) If broadheads still hitting to left and on same horizontal axis (if right handed), Too stiff of Spine for your arrows (increase poundage, point weight, or move rest towards riser at small increments of 1/32")
You usually make adjustments in the direction your arrows are hitting in relation to aiming point AFTER a good group is shot.
