Why does my floor not show the material in game?

Hello! I have a floor with a material added as you can see in the screenshot, but in game it is not showing. Everything is saved and pushed. How do I get this floor to show in game like it is in the editor?

To anyone who also comes across this issue, I restarted UEFN and when I returned the floor materials were actually not attached to the floor floor pieces I had (so they had no material like it shows in game). I re-added the floor material and it worked just fine after that.

TLDR: Restart, re-add floor material
