Only 1 comment at loading

I have set it up on this page:
https://autoimmunecounseling.com/testimonies/

And its only loading 1 comment at the start, how do I make it load all comments?

Here is the shortcode I am Using:

[wpdevart_facebook_comment curent_url=”https://developers.facebook.com/docs/plugins/comments/” title_text=”” order_type=”social” title_text_color=”#000000″ title_text_font_size=”22″ title_text_font_famely=”monospace” title_text_position=”left” width=”100%” bg_color=”#d4d4d4″ animation_effect=”random” count_of_comments=”10″ ]
