All pages on my website have “Header visibility and transparency” set to “Transparent Header”

I am using a TEAMS plugin to display a new teams taxonomy and team members profile pages which users a custom PHP page (not an enfold page)… this page starts off with:

<?php
namespace ots_pro;
?>
<?php get_header(); ?>

When using the “Get_header()” as suggested, it only pulls though as “no transparency”. How can I use get_header and have Transparent Header?

I’m trying to find out what attributes I need to add to this page so it fulls through the header as transparent.
