Short code is not working on ANPRESS Page

Hi Anspress team,
I have following shortcode coded now :
[anspress hide_list_head=”true” category=\’question\’]  + some extra CSS
I see following page is broken when you navigate o Answer tab in sidebar.
https://whatsq.com/education/aluminum-a-very-reactive-metal/
Whereas , following page looks fine.
https://whatsq.com/question/what-is-the-corrosion-of-aluminum/
