The code is not the same in the two templates.
in the file
/plugins/system/t4/themes/base/html/layouts/t4/element/offcanvas-toggle.php,
there is no line of code that says
<span class="t4-offcanvas-toggle<?php echo $lgsc ?>"><span class="toggle-bars"></span></span>
I went ahead and created the folder element then commented out the line
<span id="triggerButton" class="btn js-offcanvas-trigger t4-offcanvas-toggle<?php echo $lgsc ?>" data-offcanvas-trigger="off-canvas-<?php echo $oc_effect;?>"><i class="fa fa-bars toggle-bars"></i></span>
and added this line
<span class="t4-offcanvas-toggle<?php echo $lgsc ?>"><?php echo JText::_('COUPON<br />CENTRE') ?></span>
but it broke the template. The slider disappeared and the COUPON CENTER LINK does not work.
