That is the infamous "face reversal" problem that is inherent in ZBrush. What happens is that the morph flips the points from one side to the other. There are a few ways around it ... (1) ZBrush has a script that fixes the problem. See the attached thread for more info. (2) You can re-import the morphed head back into ZBrush and then resave it again. That will save the morph you already did. Or (3) To get around using the script, and for doing multiple morphs of the same body part (such as the head), import the body part into ZBrush and save out the "reversed" head BEFORE you do any morphs. Then import the reversed head for any morphs that you do later on.
