Runaway closing tag in checkout template

-- url of the page with the problem -- : analoghifi.no/
-- HikaShop version -- : 2.6.0
-- Joomla version -- : Joomla! 3.4.4 Stable [ Ember ] 8-September-2015 21:30 GMT
-- PHP version -- : 5.4.16

-- Error-message(debug-mod must be tuned on) -- : None / Failes to render in IE11

There seems to be a bug in 2 of the templates for checkout
checkout / step.php and checkout / shipping.php

step.php has a condition for if(HIKASHOP_RESPONSIVE) where a UL-tag is declared but not terminated
shipping.php also has a condition for if(HIKASHOP_RESPONSIVE) where an End-UL-tag is declared but not started

UL-tag in step.php is closed automaticly because it resides in a div-tag (hikashop_cart_bar) which is closed after the last -li-tag. The closing UL-tag in shipping.php becomes redundant because there is no opening UL-tag (causing IE11 to fail to render the page)
