Limit the term value to display last term

I have a Refinement webpart that is display the all the refiner for Country and I just need to show the last term.

Here is the display now for Country. I need to display last term. All the post refer to XML but the webpart does not have the editor. I am not using the Search Center template so that may be reason I do not see the option. Any idea on how to make this display correctly. Please reply with instructions if possible.

Here is the Webpart options
