How to disable comments on a single post page

Heys guys. On my website https://www.rapforthemoment.com whenever I post a comment on my Rap Blog page, in response to one of my articles on there, the comment shows up on all of my single post pages (Activity, Callouts, Crews). The comment appears randomly on the bottom of the page. How do I stop this from happening? I only want comments on my rap blog page in response to articles.

Thank you in advance for your help.
