"Edit Distribution" doesn't open a window for edits
I know that to choose which address to use for someone in your address book who has multiple email addresses, you need to open "Edit Distribution." (FYI, I'm not in icloud and am not using smart groups.) When I click on "Edit Distribution" absolutely nothing happens, so I can't edit. Tried restarting, no result. Can anyone suggest what I should do?
