minutepapillon on "Text Widget : Content appearing Before widget tittle"

Hi,

To include the Facebook/Twitter share buttons in text widgets, I created a shortcode.
When I put that short code in the text widget, the title ("partager") appears before the buttons ... strange ...

url : http://www.voirleloup.com
(in the footer right column)
It is not a css problem as the div containing the buttons is before the div containing the tittle ...

Any idea ?
thanks

shortcode code :

/*-----------------------------------------------------*/
/* share
/*-----------------------------------------------------*/
function guigui_share($atts, $content = null) {
$output = get_template_part('template-part-social-share','childtheme');
return $output;
}
add_shortcode('share', 'guigui_share');

template-part-social-share code :

<div class="tt-share clearfix">
