Can't edit or delete Menu Items

I have used the Default Menu Links option which comes with OG Menu and it did correctly create menu items for each OG Menu. However, I have found that while I can disable a menu item, once created, these menu items can not be be edited or deleted.

This may be the default way Drupal Menus work, but it was an issue for me when I wanted to change the url of one of the links (an not be a global change). Instead of being able to edit it, I needed to disable it and create a new menu link manually.
