Facebook share option does not work properly

I have a problem with the facebook share option.

The like function is no problem. It will display on facebook the right easyblog postings.
The share button however, always takes the general site metadata and general icon of the site.

I have tried all possible settings, but with no result. For one postings I got it to work, when entering a menu id in the seo settings at easyblog settings, but then it only works for that easyblog item. the rest will not work. That is no solution :-(

It drives me crazy! I dont want to like my postings. I want to share them on my facebook.....

I give up after spending multeple evenings on this issue. I hope someone can help me. The settings of easyblog are now completly wrong. no easyblog posting can be shared normally right now. Always the global site metadata is taken...
