Responsive ShortTags are not working

Hey I’m using owl carousel for wordpress 4.8, the all responsiveness shortTags (items, itemsDesktop, itemsDesktop, itemsDesktopSmall, itemsTablet, itemsMobile) and autoplay are not working at all, other short-tags are working fine such as “owl-carousel category” here is the code, can you please take a look and tell me what am i doing wrong here.

<?php echo do_shortcode(‘[owl-carousel category=”feature” singleItem=”false” items=”4″ autoPlay=”true” navigation=”true” pagination=”false” itemsDesktop=”1199,4″ itemsDesktopSmall=”979,3″ itemsTablet=”768,2″ itemsMobile=”479,1″]’)?>
