[Plugin: WP Biographia] Author Page Problem

Hello, I’ve just started using this plugin, so this is probably a mistake on my side. I’m trying to display the biography box at the top of author pages, but I don’t want boxes to show after all of the posts by that author. I’m using the Gantry Framework and it’s basic theme. Now whenever I add
<?php echo do_shortcode(“[wp_biographia]”); ?>
to my author.php, boxes are appended to all of the posts as well as the top of the page. If I omit “echo” and leave “do_shortcode…” nothing is shown at the top (expected), but boxes are again appended. Is this by design?
I also figured out that if I add
$this->is_shortcode = false;
before return of
function shortcode ($atts, $content=null)
in wp-biographia.php, everything seems fine.

Thanks,
Mike.
