Facebook "Like" Thread Title is Forum Name not thread Name

Hello guys,

Maybe you can help me with this...

I was running 4.1.3 and found a issue in the facebook like button, so I upgrade to new version to see If fix the issue, but Im now running last version (4.1.5) and the issue continues... Can someone help me?

The issue:
I've enabled the vBulletin Facebook feature and have it working, except that the title shown on Facebook is the Forum Title, not the Thread Title when liking a thread. The link works fine and goes to the correct thread though. Basically, I get on Facebook "Sofia Andrade likes Viciados no Sexo." instead of "Sofia Andrade likes Thread Title.

The same happens with the description, the description shown on Facebook is the Forum Description, not the Thread Content...

I've searched through this forum for info, but can't find anything that fixes this. Please help.

Btw, this is my code source from a thread page:

<meta property="fb:app_id" content="254054151278952" />
<meta property="og:site_name" content="Viciados No Sexo" />
<meta property="og:description" content="Viciados no Sexo é o melhor forum de sexo em Portugal onde podes encontrar milhares de utilizadores que partilham fotos e videos de sexo gratis, e discutem todo o tipo de assuntos sem tabus. O registo é gratuito." />
<meta property="og:url" content="http://www.viciadosnosexo.com/forum/showthread.php/131221-Estamos-de-volta-!!!" /> 
<meta property="og:type" content="article" />
<meta property="og:image" content="http://www.viciadosnosexo.com/forum/images/facebookvns.jpg" />

Code (markup):

Thats why is not appearing the thread title and description... as we can see, only show website name and description...

 

Btw:

Testing the URL at http://developers.facebook.com/tools/lint/
