@foone Wisconsin allows non-binary "X" gender markers on driver's licenses. Super uncommon and annoying to get, but technically possible.
The card will come with the correct letter on it.
But the temporary license they print for you there, which appears to have an image preview of your new card, is incapable of having an X so will show (presumably) whatever letter used to be there.

Not quite as good as front not matching back, but still pretty wild.
