CoursePress Pro Bug: Extra content displaying below the footer

For some reason, my theme is displaying extra content below the footer section on individual unit pages. I am using CoursePress Version 1.2.3.5 with a child theme to the CoursePress theme. I have looked in my footer.php file and in the single-unit.php file.

There is nothing after the <?php get_footer(); ?> in the single-unit.php file.

My footer file is as follows:

<?php
/**
 * The template for displaying the footer.
 *
 * Contains the closing of the #content div and all content after
 *
 * @package CoursePress
 */
?>

</div><!-- #content -->

<div class=&quot;push&quot;></div>
</div><!-- #page -->

<footer id=&quot;colophon&quot; class=&quot;site-footer&quot; role=&quot;contentinfo&quot;>
    <nav id=&quot;footer-navigation&quot; class=&quot;footer-navigation wrap&quot; role=&quot;navigation&quot;>
        <?php wp_nav_menu( array( 'theme_location' => 'secondary' ) ); ?>
    </nav><!-- #site-navigation -->
</footer><!-- #colophon -->

<?php wp_footer(); ?>

</body>
</html>

I hope that the screenshot clarifies what I am experiencing. Again, it is only on the individual unit pages.
