Horizontal dropouts, in combination with an incorrectly dished wheel makes it easy to center in the chainstays while the error will remain at the seatstays.
Go back and perform the two wheel tests I described earlier and report back.
However, keep in mind that since you can always center in the chainstays with horizontal dropouts, it's very possible that the triangle is offset to either side. Do the dish test and report back, then we can look at various frame checks.
