Renasrenas,
Very sorry for not getting back to you sooner! I'm glad to hear you think you've gotten to the root of the issue. If you think you're still having problems or have any other questions, just let us know. The v4.3 release is much more agressive with it's Open Graph tags and will actually help to 'fix' bad tags on the page. It won't be perfect, but will hopefully help improve the problems with some extensions.
Thanks, and good luck,
Alex
