I am trying to create a Menu with Subcategories but the Menu title appears with the subcategories... Why?

I add a sidebar block called: Regions

Under Regions the categories and subcategories to read:

Continents
-Asia
-Europe
-North America

Countries
-England
-U.S.
-Spain

But instead my categories read:

Continents
-Continents
-Asia
-Europe
-North America

Countries
-Countries
-England
-U.S.
-Spain

This obviously happens because when I go to Primary Links and "add item" I have to create a path (thus a page, for my Main Menu Item) before I create Menu Subcategories. I can't just create a main title for my categories.

My Goal: when I'm all done I would like to have my Menu Item read:

Continents
-Asia
-Europe
-North America

But again, "Continents" still shows up under "Continent" title.. so I literally have two "continents" titles

What am I doing wrong here! Thanks so much
