HALP!!!

Okay so I think I have borked my game. Or maybe not, but either way someone is not right. Basically, no grey hairs are showing up for females. It's not that bad because some of the custom greys are still in the custom bin, but seriously. WHAT DID I DO? And how do I fix it? Can any other simmers out there help?

Does this make any sense? Here's a pic, apologies for the shitty quality. SEE? Where are all the elder hairs? They show up for the males, why not the females? Am I being an idiot, and is the fix really obvious? I don't know...
