In the map image the place represents having buildings but the place is without them.

I can confirm that. I noticed that, too, right before the companion update but forgot about it
These missing structures on the map have been there for a long time, they came with the New Dawn update. There was a big square hole in the ground before. But never buildings.
Looks like an area that’s currently being worked on.
Not a bug tho, so I’m closing this report.
