Hello Seeder98,
From what you describe and the screenshots that you posted, whenever you move a point light to either the left or right of center screen you get a blackness or a a circular black layer appears.
It appears that your layers are not being separated on screen. If you move your light then the other layers are visible.
I would like to test this in a controlled test on my machine.
If you would link me your .uproject file, your content and config folders, and your DxDiag of your machine. I will then attempt to recreate the issue you are having in a project on my computer.
Thank you,
