Help needed with lighting

I’m a student, working on a game for a course I’m taking and I’m running into an odd error. I decided to make a night level and followed the tutorial at UE4 Tutorial: Night Time Lighting - Starry Sky with BP Sky Sphere Part 1/2

I’ve done the best I can with following the directions even though it’s several versions out of date and nowI have a not bad night sky in the editor.

Anyone have any clue what I did wrong with these pictures?
