What am i doing wrong with stationary lights and shadows?

So guys, I have set the starter content map’s light to stationary “As per default” And multiples the floor four times and i’m still a bit of an unreal engine noob so I’m learning, And I haven’t quite yet dived into how to place lightning in the room, So on the far wall panels, Something like this happened.

Any idea how to fix it?

Also, This how the room is laid out so far

Thanks for your time.

I solved this by the way, It’s just that the engine was on low quality by default due to the potato status of my laptop, I’m working on it temporarily till i get my new PC. Thanks everyone.
