Sidebar not showing on CPT

Hi,

I may have missed post on this already but didn't see one in the search.

I have a CPT (wpfc_sermon) generated by a third-party module (Sermon Manager - https://en-gb.wordpress.org/plugins/sermon-manager-for-wordpress/).

I have managed to integrate it into GP using module provided filters and GP provided filters so that it displays Archive and Single as a GP Archive & Single. However, I cannot get a sidebar to display on Archive page or Single posts, and I'm not sure why.

Sidebars work on normal posts, just not on this CPT.

The code for integration is below, do you see anything obvious.

add_filter( 'generate_blog_columns', function ( $columns ) {
    if ( is_post_type_archive( 'wpfc_sermon' ) ) {
        return true;
	}
    return $columns;
});

add_filter( 'generate_sidebar_layout', function( $layout ) {
    // If we are viewing search results, set the sidebar
    if ( is_post_type_archive( 'wpfc_sermon' ) || is_page_template( 'content-sermon-single.php' ) || get_post_type() ==='wpfc_sermon' ) {
        return 'right-sidebar';
    }

    // Or else, set the regular layout
    return $layout;
 } );

add_filter( 'sm_templates_wrapper_start' , function ($content) {
    ob_start();
?>
	<div id="primary" <?php generate_do_element_classes( 'content' ); ?>>
		<main id="main" <?php generate_do_element_classes( 'main' ); ?>>
<?php 
    do_action( 'generate_before_main_content' );
	return ob_get_clean();
});

add_filter( 'sm_templates_wrapper_end' , function ($content) {
    ob_start();
    do_action( 'generate_after_main_content' );
?>
	</main><!-- #main -->
	</div>
<?php 
    do_action( 'generate_after_primary_content_area' );
    generate_construct_sidebars();

    return ob_get_clean();
});
