Hi Guyos, Welcome aboard.
I can think of 2 possible causes.
1. The jig is not true and square. I'm not that familuar with honing jigs, but check it to make sure that it is true. Even though it is new, it could be miss aligned.
2. You say you're using waterstones. Possibly your stones aren't flat. If you are starting with a course grit (800-1000) then working your way up to fine (8000), each stone has to be dead flat. If the iron in your jig is square to the jig, if the jig is true, and the stones are flat, then it should hone true.
