That doesn't seem like a setting issue but rather some sort of bug. Unless you managed to somehow get a negative light radius.
So...reinstall / check graphics drivers I guess? Beyond that, no clue. Certainly not normal though.
After all, everything else is well lit it seems so overall brightness isn't the issue.
What is your operating system? Do you have HDR settings turned on? HDR settings are great for quality image but they also increase the dark areas. If you do have HDR on try an area you know is dark with with it off.
