Same comments on every post

I’ve been using Disqus as my commenting system but I’m facing a problem with post’s comments. Whenever I comment on a post, it shows in another post as well. For some reason, the comments from one particular post started repeating on some of the other posts. Here are the post links with repeated comments:

Please respond to the query ASAP.
