Posts in category protected when they shouldn't be

I have membership plugin activated with the following settings:

Two access levels: Visitor and Full Access
Guests are set to visitor level
All categories except visitor category are protected from visitors with positive rule
Full access level has a positive rule allowing all categories.

When a user logs in, they can view a list of all posts in a category. When they click on one of the posts, they are denied access and redirect to the protected message even though they should have access. I am running the latest version 3.0.2
