No lewd expression on my female MC in AAF sex scenes.

[RTX3080TI]

There is no lewd face expression in AAF sex scene (e.g one of Leito's Animations and I know it's already baked in ) on my female MC, she just smiles all the time.

But it works just fine if I choose some other random female NPC in the same AAF scene. Meanwhile if I just play idle of the said animation on my female MC, the lewd expression is back as well). Some help?
