I have a Mathews Dxt. I am shooting Carbon Express Maxima Hunters and a Mathews HDII rest. Why is it that when I shoot my Arrows, 2 out of the 3 times i shoot it, it goes into the target crooked like sort of slanted? And remember this im am shooting from astraight on position.Is it because of my rest or what is it? I dont want this problem to keep occuring.

For example.

[]- the block
/- the arrow.


Well it isnt that bad of a slant but its the closest i can get to it.
