Pages that a user group has access to not showing up on edit screen

I have created a user role called Administrative Director, and have created a group for it in User Access Manager. I have given this user group access to all of the pages on the site, however in wp-admin, when I go to ‘Pages’, I don’t see all of them listed. There is no consistency with what pages show up, and what pages do not. This is a multi-site installation, and I have the plugin network activated.
