How do I send eyebrows from Blender?

How do I send eyebrows from Blender?

I imported a CC5 model into Blender using Blender DataLink.

I was able to modify the mesh and return the body to CC5 using DataLink Options → Mesh.

However, I can’t send the eyebrows. When I select the eyebrows and go to DataLink Options → Mesh,
an error message window appears in CC5 saying “Unable to determine source mesh for replacement Brows_filled_in /Brows_Filled_in,” and I can’t send them.

Even exporting from Blender as an OBJ and replacing it doesn’t seem to work, and although the mesh exists,
the eyebrows become transparent.

How do I send (modify the mesh of) eyebrows from Blender?
