PPV editor button question

Hi !

I am doing some tests, but I'm having a problem with the button in the editor. Everything seems to work for the whole post/page, but not when I try to hide only a small block on the page (with the PPV button in the editor).

Here is my shortcode : [ppw id="131684747" description="video" price="10"]This content is protected[/ppw]
and here is my page : http://loickernen.com/wude/espace-adherent/

I don't see the content as locked. Am I doing something wrong ?

Thanks !
