News articles doubled? Possible problem.

I read the latest news article called "Does it feel like Christmas?"
I placed two replies (which I believed to be the first ones), then returned to the front page.
When I clicked the link again, my replies were missing and there were six others' replies instead.
I checked around the page and studied the links. Here's what I found.

Same article, but different pages and different replies.

Also:

seems to be a blank news article.

Sorry for the late reply:
