Question AR Foundation Facetracking- How to replace 'default face' mesh with your own?Mesh Rotation incorrect

If you see attached image, I think I've replaced the 'default face' mesh for AR Foundation Facetracking with my own.
It's a nose, but it's facing the opposite way.
I cant seem to find where I'd be able to change it's rotation.
Literally changing the prefabs rotation doesnt do anything. It still keeps the nose 'backwards'

Thanks
