Social Share icons on Portfolio Items

Hey guys, I recently updated to the latest version 3.1 and one of my custom functions has broken.

I was using this in order to display social sharing links on portfolio items:

add_filter('avf_template_builder_content', 'avia_add_social_toolbar_template_builder', 10, 1);
function avia_add_social_toolbar_template_builder($content = "")
{
if(is_singular('portfolio')){
	$content .= avia_social_share_links(array(), false);
	$content .= '<div style="height:1px; margin-top:50px;" class="hr"></div>';
}
return $content;
}

The code still works in the sense that the icons are presented, however, after the update the icons are now all the way at the top of the page (where the content begins) and not at the bottom of the entry as it used to.

I would appreciate any help in getting this working.

Thanks!
