Ceiling Tiles Are Two Different Colors...

Okay, first off, I’m playing The Sims 4 on PS4. So, I was building in San Myshuno, in the 21 Chic Street Apartments, more specifically I was building in the 1310 Chic Street apartment. Everything was going great, so I thought I would see how it looked in the free camera mode. As soon as I entered free camera mode, I noticed that the ceiling “tiles” were part white, like they should be, and part blue... The blue was like a concrete texture though, definitely didn’t look like the same texture as the normal white ceiling. I am so confused as to why this happened, or if it’s even a bug. Any ideas on how I should go about fixing this?
