That isn't the way it works. I'm sorry if the way I worded my response misled you.
If you want to change from:
You replace it with.
One replaces the other. It's not a case of just pulling out the text string "England".
One could try to do a search and replace in the People Workspace, but I don't see how that could work on the country, as you would have to remove the preceding comma and space - I don't see what one could replace the comma-space-country with. I guess you could try replacing it with a space or a "sticky-space", but I don't know if that would work.
