It only recently occurred to me that it might be a bug but during one of my playthroughs the description of the warehouse on the map when the scenario there is 3 armed thugs that attack on sight did not contain "Danger" all other locations like that have that in the description below Lots of food, Lots of parts etc. And that was before the first visit, I know that thingy disappears after you kill all armed people in a location. I didn't check if it happens every time though because I can't seem to get the warehouse again lately
