How can I remove "Site Title"?

I have the following code embedded in my theme’s functions.php file:

add_filter( 'gtc_pages_filter', 'gtc_add_viewcount_title' );
function gtc_add_viewcount_title( $pages ) {

    if ( !$pages )
        return false;
    // loop through the pages
    foreach ( $pages as $key => $page ) {
        // and add the page count to the title value
        $pages[$key]['children']['value'] = $pages[$key]['children']['value'] . ' ['. $pages[$key]['children']['children']['ga:pageviews'] .' Views]';
    }
    return $pages;
}

Also the following code is embedded in my theme’s single.php file:

<h3>Top-Viewed Posts Last 30 Days</h3>
<?php echo do_shortcode('[google_top_content pageviews="5" catfilter="3173" contentfilter="post" number="10" showhome="no" time="2628000"]'); ?>
<h3>Top-Viewed Posts Last 12 Months</h3>
<?php echo do_shortcode('[google_top_content pageviews="5" catfilter="3173" contentfilter="post" number="10" showhome="no" time="31536000"]'); ?>

For some reason the display of top posts still repeats the site title in all of the listings.

Please advise how to remove site title from the listings.

Thanks in advance for your advice.
