Since you do appear to have a Genesis 8 figure loaded into the scene (based on the scene pane in the upper right) this does suggest (as Joraell said) that there is something wrong with your installation of the Genesis 8 figures - basically, it doesn't seem to be finding the meshes. What I would suggest is that, if you're using DIM, that you uninstall and re-install the Genesis 8 Starter Essentials - they just didn't get set up properly.
