Posts from blog to Facebook contain wrong image

Can WPMU Dev assist us in resolving a problem? We are having issues when posting to Facebook. Facebook does not take the designated images from as part of new posts to our Facebook community page, This happens most of the time but not every time.

We use JetPack and the Publicize button, and when we create a post with a featured image, Facebook often does not pick up that image in the post, but instead captures a snippet of our header. You can see the results on the most current post (and several other recent posts) on Thanks for whatever help you can give us; we've tried a lot on our end but have struck out.
