Misplaced Shadows & Inaccurate Lighting

Just trying to Understand what I did wrong, I used the Architecture Props to get 2 walls and floor, etc. And the shadows are just acting on their own Independently, I just want two walls and if you re-size just one it puts the Tiling out of place, Anyone know what I’m doing wrong (Or what I need to do?)

Take a look at this: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums

If that doesn’t help please post some screenshots as this is often the most helpful way to diagnose and offer tips for static lighting questions.
