Hey there AppJunkie ...
I'm having this issue too. The odd thing about it is that when using my iOS devices, all of the contacts (and other address books) all show up exactly as I expect and want them to. Now, on Mac OS X, that's a different story. There doesn't seem to be the same functionality between the two Apple operating systems.
Quite frustrating, as I have clients who expect these to work with no problem on their Mac desktops, since their mobile devices work perfectly. They let me know their mobile devices work, and they want the problem fixed. I have nothing I can say or even suggest. It is very discouraging.
I have not been able to find any fix or workaround for this, unfortunately.
