Shortcode filter showhome=no not working

Calling the shortcode with the following line… it works perfect, but it’s still showing the homepage in the results. Any ideas?

<?php echo do_shortcode('[google_top_content showhome=no number=6 time=86400 timeval=7 titleremove=" | Health Impact News"]'); ?>
