What arrows? Brand and spine. Point weight. Type of rest.
You might need to start from scratch with the setup. Sounds like the rest might be left of center on the bow.
Without a peep I wouldn't worry about the POI of the arrow right now. This might correct itself once you have a peep in the string. I'm guessing that possibly the bow's draw length is too long for you causing you to float your anchor on longer shots, but this is purely speculation at this point.
