now that you said that I think you might be holding the grip wrong, you where throwing everything out of alignment,,,, do you see any weird strike plate wear on your bow that wasn't there before?
try drawing the string back and turning your bow hand just a little as if you had a dirt bike with a throttle on the left you want to be giving it some more gas..
I'm wondering if your dinging the shaft with the back of the riser at release usually a knock sound is heard.
when I first start drawing back I hold the grip loose and it aligns perfect because of the pressure form drawing,, then depending on the bow I go to the grip I like for that bow.
