Well the front wheel does sit offcentre, as the brake pad hit (a plain block - cannot move the wheel) when flipmounted proved.Possible reason for deliberate off-centre build? None I can think of. Will cause some additional tyre wear.
Exact centering of the hub doesn't matter as trueing the wheel will compensate for any small anomaly (rim brakes).
You do seem a magnet for problems with this new bike.
