Inconsistent Behaviour

HI,
I installed the Facebook Comments on my blog and i see that they comments do not show up on all pages. It only shows up erratically. Its entirely possible that I have goofed up during installation, please help.

Example of a page where the comments appear:
https://www.motorcycl.in/new-bmw-r-1200-gs-adventure-2014/

Example of a page where the comments do NOT appear:
