Silly question, but do you have any groups created?
If you do and this still happens, try switching to the old address book interface (Options -> Preferences -> Other options)
In the old interface, you add contacts to groups by going to the properties of a contact (right click), and using the "..." button by the Groups field in the General tab.
Also, when creating groups make sure to deselect the option "Hide items if not explicitly selected", which will make contacts added to a group visible fr om the general address book. You can modify this field for existing groups in their Properties (again, right click). See this post (and whole thread): https://www.ritlabs.com/en/auth-forums/forum4/topic15701/message53827/#message53827
Miloš Radovanović, thanks! Switching back to the old interface allowed me to proceed with the changes I needed to get done.
(I had looked in the preferences for a switch like that already, but not found it, until you gave me a specific place to look and the assurance that it was there to be found.)
I do have groups created. In fact, what I have - which sounds like it might be relevant? - is a system where I put every address in at least one group and have all the groups set to "hide items if not explicitly selected", because something about having them all in a disorganised clump was annoying me. (It was long enough ago now that I don't remember specifically what that was.) What I've been trying to do was more precisely move an address from one group to another.
