Pagination not working properly in A+

I cant get the pagination to work proporly on http://onlinereading.webinnovate.dk/.. I've put in this shortcode instead [app_pagination step="1" month="1" anchors="0"], but now it reloads the page and starts from the top - instead of just loading the booking system, like it normally does. This is how it look like with the new shortcode:
http://onlinereading.webinnovate.dk/bestil-tid/
Normal shortcode:
http://onlinereading.webinnovate.dk/make-an-appointment/

I would really like it to just load normally so it doesn't update the site and keeps being in the view of the booking calendar.

Have a great day..

Best Regards,
Rasmus
