In the public vew, (which is the vew that we all see), it is standard practice to not have the spouse showing up. That is the way the software works, and I don't believe that can be changed.
Even when I look at my profile in the public vew, my spouse does not show up!!
But when I look on the privacy tab, (or private view) he is right where he should be. But only I can see him.
If you go back to your privacy tab, the spouse will be there but YOU are the only person who can see that.
