As Chombi said, if the wheel is dished correctly but it is offset at the top of the wheel, then one of the DOs must have been moved up or down. It's hard to imagine how that would happen without visible damage to a seat stay. The other possibility is that the wheel isn't dished correctly. In that case it would be offset at both the top and the front but you (or anyone) might correct for that simply by repositioning the axle before tightening the QR skewer. Since we don't know how you are positioning the wheel we can say no more about that.

However...if the stays are just pushed to one side you can re-dish the wheel to re-center it. As long as you don't move that wheel to another bike or dish it so much that the drive side is over-stressed it will end up perfectly aligned. The DOs and therefore the entire axle and hub will be a bit to one side, but the dishing will have brought it back to center.
