You're nock is a little too low, causing the broadheeads to show the error more than the field points, so they group higher.
I'd tighten the top limb bolt about 1/8 of a turn, this will raise your nock point a few thousands of an inch. The broaadhead group should come down into the field points.
If you're already maxed out with the limb bolts, just loosen the bottom bolt the same amount.
Don't turn it too much, you're pretty close as it is if you're within a few inches at 30 yards.
