Acadia is eluding to viewing issues which manifests if the preview window is not properly configured for your system.  In this case, I don't believe it's a viewing problem.  Open your Properties/Parameter panel and select V4's body, and check Morphforms>Morph++>HeadSize.  You may see that dial set to 1 instead of 0. 

Edit: moriador, the OP is already starting with a morphed V4.  That dial does appear automatically; it is not present in the base version.
