If you check in the materials window, there are actually 3 eyebrows listed (one being the "upper eyebrows"), but one of them (the last one I think) doesn't actually do anything. If you want the eyebrows that are shown on the texture map to be seen you have to do one of two things... either set the transparency of the "upper eyebrows" to 100% with no transmap set (so that it will disappear completely once rendered) or morph the eyebrows away. If you have Victoria2 there is a "browsgone" (I think that's what its called) morphed that pulls the upper eyebrows into the head so you can't see them. Otherwise they block the view of the texture map underneath... I hope that made sense and was helpful.
