Hi Dallas,
How many times did you run the import? Unfortunately the way the WordPress importer (which our importer is built ontop of) works when it comes to menus is, if it finds a menu with that name already, it will add the menu items from it – even if they already exist.
The quickest way to sort this is to go to Appearance > Menus, and then click “Remove” on the ones you don’t want: https://www.dropbox.com/s/flvypar515riwov/Screenshot%202014-07-04%2003.32.04.png
Then save the menu and it should be how you want it.
Hope that helps.
