Missing something

This looks great, but for some reason this is not working for me. I’ve gone over the instructions and examples multiple times. I’ve triple checked the profile metakey value and custom post type slug. I even tried removing the post type slug and leaving it blank, which should make all posts selectable. However, when i go to edit profile, the profiel field drop down value just shows “relationship” the place holder text. It doesn’t seem to be working. Any ideas of what I could be missing beyond those obvious things which I have triple checked.
