How can I determine where this menu is coming from below the Q&A plugin content?

Hi, I'm using the Customizer Theme and when logged in viewing the Questions page there is a sidebar and menu appearing below the question content from the Q&A plugin.

How can I find out where its coming from so I can remove it?

I looked at the Questions page I had created and temporarily set it to draft and the questions page still appears for the questions content.

Any thoughts?
