I suspect the original town used for St. John's once had some merchant stalls, which were deleted. The shadows at day show their location. And if one is accompanied by crewmembers, the street merchants are also there.
If possible you can:
A. Bring back the stalls
or
B. Delete the locators for the street merchants and remove the stall shadows in the shadow textures.
