Social icons don’t change because they are not “Follow icons” but “Share” type. So if you want to make them links to your social profiles you need to change file basel/woocommerce/content-single-product.php
and replace this line
<?php echo basel_shortcode_social( array( 'type' => 'share', 'size' => 'small', 'align' => 'left' ) ); ?>
with this one
<?php echo basel_shortcode_social( array( 'type' => 'follow', 'size' => 'small', 'align' => 'left' ) ); ?>
To prevent loosing changes after update we suggest you override this file in your child theme.
