Why pagination is not working in Advanced FAQ Manager?

BWL Advanced FAQ manager WordPress plugin provides a pagination option to display FAQs. For that, you need to add two additional parameters to the shortcode. Here is the reference screenshot of the shortcode.

paginate : Set 1 to enable the pagination 
page_limit : Set the number of FAQs you want to display each page.

You can also generate the pagination code using the shortcode editor.
