Breadcrumb not working

I purchased Breadcrumb today and followed your instructions for installation and setup.

I have added the Shortcode to the bottom of theme header.php as follows

<?php get_template_part('sections/specia','header'); ?>

<?php get_template_part('sections/specia','navigation'); ?>

<div id="content" class="site-content" role="main">
<?php echo do_shortcode("[breadcrumb]"); ?>

but it does not work. I am using theme Specia and Visual Composer.

Your help would be welcome.
