Wrong Link when new window opens

Hello-
I am working in the Inovado Child theme by Minti, but I believe an expert on this forum could help me fix this issue. (I am unable to access the Minti forum).

There is a Theme Option to enter your Social Media URLs – then the footer icons open a new window directly to the Social Media site.

HOWEVER, once you click the button link, it opens a new window, BUT the Social Media URL attaches to the website URL. For example:
http://www.gatewayglobaltrading.com, opens to http://gatewayglobaltrading.com/www.linkedin.com/pub/…name…

Here is the code from the Footer.php

<?php } ?>
<?php if($data['social_instagram'] != "") { ?>
<li class="social-instagram"><a>" target="_blank" title="<?php _e( 'Instagram', 'minti' ) ?>"><?php _e( 'Instagram', 'minti' ) ?></a>

Might anyone be able to help me? Thank you!
