popup pro second popup not triggering

We've got 2 duplicate popups on the site but the second popup doesn't seem to trigger.
This was working a while back but I'm not sure if it was a recent upgrade that changed it or some other tweaks we may have made. And we have recently installed the wpmu dev dashboard.

How it should work is :
- Popup 1 is on all pages and pops up when the user clicks on a particular css. In this popup is a form which when submitted the parameter is added to the URL.
- Second popup is the same layout but always shows if there are particular parameters in the URL.

We set this up using approximate URLs based on a previous support ticket:

However at the moment is only seems to be showing the 1st popup as it only displays when clicking on the "Book a car" CSS selector.
