i'd put my money on you getting a high tear because you're getting some contact somewhere. is that bow a single or dually or hybrid? do the bare shafts and fletched hit in the same horizontal plane?

you could move your rest a little right, a little. i like coming out a little nock high and tail left, so do lots of other people, but some people like coming out perfect.

lots of people are going to suggest trying different weighted points to see if that clears it up because it suggests a spine issue. but befoe that i'd try moving my nocking pt up about 1/4" and see what happens. if the vertical tear gets smaller you know you were getting contact and that contact could be affecting everything you're experiencing.

edit: oh yeah, lowering your rest will accomplish about the same thing as raising your nocking pt. your arrow should be pretty much splitting the berger hole.
