Formatting custom PDF

I’m being asked to use a custom page template for the show I’m working on. The template is one panel per page on a portrait layout. I’ve been able to import the image of the template and size the panel to fit over top of the template image correctly. The problem I’m having is that the caption fields rather than sitting underneath the panel are now pushed to a second page. How can I get the captions to sit underneath the panel. Nothing I do seems to work? I’ve attached jpgs of what I’m getting.

Any help would be greatly appreciated…it’s this or draw everything in Photoshop…
