I think you have the JFBCSocial and JFBCContent plugins switched around.
The JFBCSocial plugin is what translates the code you posted into the Facebook widgets
The JFBCContent plugin is what automatically puts the code into articles.
I think you should publish the JFBCSocial plugin and un-publish the JFBCContent plugin.
With 3.2, we're hoping to make things a little clearer- the JFBCSocial plugin is being removed (integrated into the JFBCSystem plugin) and we'll be adding more configuration over where the JFBCContent plugin can place it's contents.
Hope that helps, but if you still have issues, let us know.
