Access to subscribe button is restricted

I am trying to insert text on my Membershipz>Welcome page to allow people who arent yet registered as Level 2 Members (Competitors) to upgrade their subscription withough showing this option to members already subscribed as Level 2 (Competitors).

My page reads like this:
[not-level-2014-world-art-championships-competitor] Show the world your creative powers and register for the 2014 World Art Championships. It is not too late to register, and you can click the button here to get started. [subscriptionbutton subscription="2"] [/not-level-2014-world-art-championships-competitor]

But, when I view the page, the subscription button shortcode reads like this:
Show the world your creative powers and register for the 2014 World Art Championships. It is not too late to register, and you can click the button here to get started. Subscribe Sorry, but this section is restricted. If you would like to become a registered user, you can click here

How do I get the subscription button for [subscriptionbutton subscription="2"] to appear? in stead of the"content restricted" text?

Thanks, Ed
