Vampire sim’s eyes changed colors

When I created my vampire sim in CAS I gave her red eyes; and they’ve been red this whole time. However I noticed when she switched into her career outfit her eyes were blue. I’ve went into CAS and changed her eyes back to red multiple times and whenever I go back into the game they change back to a human color (blue or sometimes even brown). When I looked up the causes for this online it said conflicting mods or cc but that isn’t possible since I play on xbox. Her dark mode has red eyes still but whenever she’s in her normal mode they aren’t red. Suggestions?
