How to fix this face bug?

I wanted to give a follower a different body, so I gave het hdt uunp, she already used uunp so I didn't think there'd be an issue, but then this happened.

I figured maybe it was the weight bug, so I set her weight to what it should be, but the vanilla face is still sticking around.

 

Anyone know how to fix this?

To possible problems:

 

First: Her Facegen-Data are overwritten by an other Mod. If it is this, reinstall it with NMM or put her to the bottom of the installorder in MO.

 

Second: Facegen-Data are complete missing.

Yep, it was her facegendata, I deleted it and reinstalled it and her face showed up correctly again. Thanks.
