Post/page specific slide in not working as expected

I have a overall slide-in form for people to subscribe to my blog installed.

You can see it on this page: http://www.bristolstrategy.com/2014/06/smart-way-think-lead-nurturing/

On this page I used the override settings to post a different slidein that has a CTA to get a Buyer Persona worksheet. I am using the slidein message override on that page and selected the other slide in but the main slidein for post always appears and the new one does not.

Please tell me what I am doing wrong.

Sincerely,
Dave Orecchio
