I'm trying to create a new Group from Address Book. But when completed and click on the new group created, it's blank. Here's what I did, opened Address Book, click on "New", selected "Group" and named it, clicked on "Add" and dragged who I want in that group. Clicked "ok" twice and the new group shows up but when I click on it it's empty. I followed this step from the Help menu, is there something I'm missing?

Thanks in advance.
