@monsta14: None of the settlement mods I know make any kind of UI changes, so it's very improbable that it's related to one of them. It's either an issue with screen resolution or any kind of UI modification. In your thread you mention you already tried renaming/deleting your \interface folder, which would also have been my first advice, since that's where most UI mod files should be located. But there might also be interface-related mod files in \Fallout 4\data, like a widescreen.ba2 or similar for example. Other than that, I'd probably play around with the screen resolution to see, if the upper part shows up again. And if everything fails, it's always best to go back to plain vanilla to see if the problem persists. If yes, do a complete and clean reinstall. If not, try adding in the mods in small packs or even one by one until the issue arises again, thus narrowing it down to the culprit.
