Visemes Not detecting in VCC

Hello,

Pretty new user to unity and VRC in general. Just trying to get my first model imported and properly set up in the VCC.

In the inspector when I try to set up LipSync, VCC doesn’t auto detect any visemes. I have to manually select Viseme Blend Shape, assign the mesh for face mesh, and then in the drop down menu for each viseme there are still no options. I know they’re there, I can see them in Blender. What could cause them from not appearing here?

Thanks for any help.
