Post limit not working

If you go on mobile and visit the page, the limit of posts being displayed is not working.

Here’s the shortcode

[psac_post_slider dots="true" show_author="false" show_category="true" show_date="false" show_content="true" show_read_more="true" arrows="false" autoplay="true" limit="3″ autoplay_interval="5000" speed="800"]
