My pinterest share button is overrided by Plugin button

Hi,

I have a Pinterest share button with this code:
<a target="_blank" onclick="javascript:window.open(this.href, '', 'menubar=no,toolbar=no,resizable=yes,scrollbars=yes,height=600,width=600');return false;" href="https://pinterest.com/pin/create/button/?url=<?php the_permalink(); ?>&media=<?php $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) ); echo $url; ?>" title="Share on Pinterest"><i class="fa fa-pinterest"></i></a>

but when I activate the Plugin the button icon is replaced. The new replaced code for a Pinterest icon is the following:

<span data-pin-href="https://es.pinterest.com/pin/create/button/?guid=jL9Lz6hQ5uQz-1&url=http%3A%2F%2Fmooi.e-andorra.net%2Fcarta-a-los-reyes-magos%2F&media=http%3A%2F%2Fmooi.e-andorra.net%2Fwp-content%2Fuploads%2F2015%2F12%2FCARTA-a-los-REYES-MAGOS-Calendario-de-Adviento.jpg&description=Carta%20a%20los%20Reyes%20Magos%20-%20Mooiesbonito" data-pin-log="button_pinit" class="PIN_1457654178007_button_pin PIN_1457654178007_red"></span>

You can see both the wrong and the right button in this image link:
