Sky Sphere not refreshing material

I am a beginner in Unreal and have been trying to set up lighting for my first scene. I am using the BP_SkySphere and want it to be connected to a directional light. I’ve changed the color on the directional light and clicked on refresh material in the sky sphere, but there was no change in the sky’s color. However, the sun did change color. I also noticed that when I hover over the “refresh material” box, a separate box pops up that says “false”. I’ve tried deleting the sky sphere and starting over with a new one, but I get the same results. Any guesses as to why it won’t update?
