Specific Post/Page Access Restrictions Issue

I have configured s2 using Specific Post/Page Access Restrictions, specifically two posts. I have generated the paypal buttons and added them to the Membership options page. So no problem there.

From my understanding, (and I could definitely be wrong) – That a user added to the backend of the site, by the site user, and assigned level 1, should also have access to those posts once they login to the site. I have tested this out, and have a redirect from login to the category page showing the two posts, yet when click on the title link of either post, I am redirected to the Membership options page.

SO that being said, did I configure something incorrectly or is my understanding of the plugin settings wrong.
What I read in the set up is Specific Post/Page Access Restrictions (optional)

s2Member now supports an additional layer of functionality (very powerful), which allows you to sell access to specific Posts/Pages that you’ve created in WordPress. Specific Post/Page Access works independently from Member Level Access. That is, you can sell an unlimited number of Posts/Pages using “Buy Now” Buttons, and your Customers will NOT be required to have a Membership Account with your site in order to receive access. If they are already a Member, that’s fine, but they won’t need to be.
