Can't add members to my memberships (protected content)

Hi,

Just installed protected content, have set up two levels.
I can import members to the plugin, but i can't add a membership level to the users.

The "Select membership to add" dropdown dosen't show any memberships. And i have two active.

Image showing that i can't chose any memberships: http://webbkund.se/seniornet/photos/add-membership.png

Any help is highly appriciated.
