Membership Plugin - Only allows 2 Membership Levels to be Created

Does the plugin only allow for 2 Membership levels. After I enter the 2nd Level the 'Add New' button dissappears.

I am creating a membership site that the members will get fresh content each month and they will be charged for that fresh content each month, so I need to be able to step them thru at least 12 months of Levels to achieve this.

Your instructions would seem to indicate that I can create unlimited Levels. Please Advise.
