It's not quite right, but looking at the top picture of the four, the bridge itself doesn't seem to be sitting quite square, which could explain some of the string position over the pickup. You may also have the treble side of the pickup pushing against the side of the cavity, which even if it's using up say 0.5mm of play in the pickup screw holes, can make a difference. So worth checking for both.

If the bridge isn't square, then keep one of the existing rear screw holes and plug and redrill the rest.

If the pickup isn't touching the sides, you may be able to just push it a bit more to the treble side and improve the pole alignment.
