I've ended up with two basic pages in the navigation menu and there seems no way to get them off.
The pages are just plain ol' pages; the pages are not created by a module. I am using the Drupal 7 core Book Module. One of the pages in question is a book; the other is a child page of the book. The book has other child pages which are not listed in the navigation menu. The Book navigation menu works fine.
admin/structure/menu/manage/navigation has no "Delete" Links by the pages.
editing the page, there is no "add page to menu" specified. I've even tried turning that on, creating a menu item, then turning it off again. The pages still list in Navigation.

I have the option to disable these pages, but clearly that's just wrong. Can anyone help?
