Membership Positive & Negative Rules

I am using Membership with BuddyPress and I have only one subscription option which will allow Members to use all parts of the site.

For those who are visiting only so therefore strangers, I only want them to be able to see and access the top line headers. So for example, my header tabs are Jobs, Account, Activity, Become A Member, Groups, Forums & Members. I only want those who haven't subscribed to be able to see the tabs that say Jobs & Become A Member.

I have read the manual and thought I understood the positive and negative rules for users based on their subscription but I must be doing something wrong.

I have set up negative rules on a level which should be available for those who haven't subscibed so that all of the Buddy Press tabs aren't shown publically but I can still see them even when I have logged out of Wordpress.

Can anyone help me please?

Thanks
