Hi Pas,
From your screenshot, it seems Disqus is indeed installed(http://take.ms/dnHd4). The area that you highlighted is EasyDiscuss's comment.

In your frontend, only Facebook comments is showing. If you want Disqus to show, you have to disable Facebook and built-in comments. If you don't want to disable them, you can enable multiple comment system in the comments Integration page.
This is how your frontend looks like with multiple comment system(http://take.ms/wT4lz).

Hi Raymond.. thank you so much for your quick response.

It's working now.
