Missing D4 map label on page 492

[Chriszy]

I just bought the Pathfinder 2e Kingmaker Adventure Path and was looking through the maps.

When I was looking through Chapter 11, I noticed the map on pg.492 was missing the D4 label.

I can guess that D4 should be North from D2 based on pg.497.

But that still makes me question whether this is a mistake or misprint?Any thought?

My PDF copy from September is missing it, as well, so I'd say it was a mistake.
