Really a dungeon or bug?

I am using Midgard mod for some QoL stuff and auto-marking things as I run by, saves me time marking it myself.

I have a little village in meadows close to Black Forest. My map is showing a dungeon is supposed to be there where one of my houses are?

I've been all around the hill and cliffs I live in, and there's no entrance or anything like that. Is there like, a secret dungeon under the mountain I don't know about? Or is this a bug with the mod.

One side slopes up from meadows, the left is a cliff down to a narrow creek, the right is just meadows full of trees, the back slopes downward toward the Black Forest. But this dungeon marker is smack in the center of my village.
