Membership 2 Pro Adds 3 Pages to All My Menus

I've installed and configured Membership 2 Pro and for some reason, it's added 3 pages to all my menus. All the menus have the checkbox:

[ ] Automatically add new top-level pages to this menu

Are all left unchecked. The three pages it added to all my menus are as follows:

  1. Account
  2. Membership List
  3. Registration

Why were these added to all menus? Is it a setting I overlooked when configuring the plugin? How can I prevent these pages from being added to menus in future installs?
