Comment count not showing in single posts meta

Hi,

I'm trying to get the comments count to show alongside the author name and updated date in single posts but it doesn't seem to work.

As you can see, the comments count just doesn't appear:

Here is the code I have:

add_filter( 'generate_post_author_output', function( $output ) {
    if ( ! is_singular() ) {
        return $output;
    }

    return sprintf( ' <span class="byline">%1$s</span>',
        sprintf( '<span class="author vcard" itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author">%4$s<a href="%1$s" title="%2$s" rel="author"><span class="author-name" itemprop="name">%3$s</span></a></span>',
            esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
            esc_attr( sprintf( __( 'View all posts by %s', 'generatepress' ), get_the_author() ) ),
            esc_html( get_the_author() ),
            get_avatar( get_the_author_meta( 'ID' ) )
        )
    );
} );

add_filter( 'generate_header_entry_meta_items', function() {
    return array(
        'author',
		'comments-link',
		'date',
    );
} );

add_filter( 'generate_footer_entry_meta_items', function() {
    return array(
        'categories',
    );
} );

And here is the CSS I have:

.byline img {
    width: 35px;
    height: 35px;
    border-radius: 50%;
    position: relative;
    vertical-align: middle;
    margin: 0 10px 0 0;
}

.single-post .entry-content img {
	  box-shadow: 0 5px 15px rgba(0,0,0,0.5);
}

.entry-meta a{
	margin-right: 10px;
}

.single .comments-link {
    display: inline-block;
}

Any idea what's wrong?

Thanks
