Level Shortcode problem!

Hello...

I'm trying to limitate the access to some content inside a page. I have 2 premium levels that can acces to this content, called for example premium 1 and premium 2. When I use the shortcode for premium 1 to wrap up the content everything is fine for that subscription, but when I use both shortcodes, for premium 1 and 2 in the same page, the shortcodes are blocking themselves and the content is not available for any level. What can I do to fix this?
