This happened to me today too and now I'm stuck like that, went from female face 9 to female face 1. I played for at least 12+ hours without the issue but sometime after I unlocked the barber (no idea if it's related or not) and played around with it, I noticed. Actually I noticed it first when I loaded up the Division 2 on a different PC.
Needless to say this extremely annoying. I pay for in-game clothing and visual modifications so it goes without saying that I want to continue wearing the face that I picked.
