I have supporter and supporter advertising.
Sites created on the network can remove advertising on 1 blog for every site that is a supporter site.
i was testing this out and when im logged in with the testing site to test this feature i go to back end > supporter > disable ads
then i come to a screen that says you can disable ads on 1 site - hit search to find a site to disable ads on.
after hitting search ALL NETWORK SITES show up.
the only sites that should show up are the sites of that one user with the test site.
i did not change any permissions.
