On OpenGraph settings

Wrong Image Shown at Facebook for Ultimate Facebook Featured Image
This image is the right sidebar ad Image
before the update it showed the Header image.
Would like it corrected now that I have time to deal with it.
This is the Images that should be shown (featured Image)
I used this http://developers.facebook.com/tools/debug
for the image above to check the properties
I had the same problem on another site I thought it was fixed with a theme change but was not.
I'm now using eVid By Elegant Themes
on both sites
