[support] Messed Up Navigation Menu - Multiple "Add Content"s

[ Ubuntu; Drupal-7.15 ] Check out the last few entries in my "Navigation menu": (1) I don't know how I got two extra "Add Content" entries, nor how to remove those two ... (2) How can I get rid of the first (disabled) "Add Content"? I don't really want any "Add Content" entries in the "Nav menu" (I've created a "shortcut" in "admin mode" to add content).
