Membership, Visitors content, landing pages

How do I use membership to UNPROTECT content that I create for landing pages. I created landing pages with the plugin http://wordpress.org/plugins/landing-pages/

I then went to view pages and it showed protected content

I then added the urls to url groups and added that to "visitors" and it showed up but the rest of my site when down.

I have all my public pages in "visitors" member access level in a positive rule, I added url group to "visitors" access level in a positive rule. When I did this the rest of my site went to protected content.

I had to remove url group from positive rule, clear chances and history and then site was fine. But I have to have my landing pages public

Please advise
