Hey David,
This is probably in a language file, but i'm not sure. Verify your attribute option names and values from within the admin, also use the attribute controller to preview from within the product catalog.
TEXT is your default values, but note that when you add the map without having selected a map, the cart does not show a map name. So I'm thinking it's a combination of language file, or attribute setting. Also, you'll want to set your attribute as required so people don't checkout without having selected a map...
