Header not displaying on page.php for listings page

Hi there,

I am using a plugin called Optima Express to display real estate listings on my website: https://dev.point59.com/

However, when I go to a single listing, the header does not load in the template file. Example: https://dev.point59.com/homes-for-sale/1311-NORTH-SHORE-DRIVE-SUDBURY-ON-P3B-1E7/2075596/273/

Any ideas on how I can force the header to load for these pages?

Thanks for the free plugin. Otherwise, it works great!
Mike
