What do these strings below the map names mean?

In Dead by Daylight, I recently noticed that in the "Match Details" tab of the settings menu (accessible in the tally screen or if you press Escape during a match), there's a seemingly semi-random string of characters underneath the map name in the bottom right. Here's a collage of screenshots to show what I mean:

At first, I thought maybe this is simply the internal name of the map in the game files, but then I noticed that I'd get different strings for the same map (interestingly, while going through my screenshots, I noticed two separate occurences of the Silent Hill map that both had the string "B_Escape_01").

My next guess would be that these are some sort of seed for the random elements of map generation, such as how the structures spawn. But in that case, I would expect them to look a lot more random and not contain any real words (and also to not repeat at a noticeable frequency).

Does anybody know what they are?
