This is something I try from time to time when I have conflict between plugins that are page/post related.
Go to the page/post and scroll down to the plugin settings area. It is best of you minimize all the settings areas so you can see what you are doing more clearly.
Then what you want to do is move the plugin that has the problem above the others, you do this by hovering over the plugin you want to move, the cursor changes to the "move" cursor. Then select and hold the left mouse button and move the settings to the top of the plugin list. This may or may not resolve your issue, but it has worked for me in the past on several occassions.
