[NSFW] Comment form formatted differently in different post pages

Hello.

For some strange reason my blog shows 3 different formatting for the comment form in different pages/posts. The differences can be seen in the latest three posts I’ve made.
It should be like it is in the oldest posts but as you can see, there are some differences like:
– Instead of “X thoughts on…” some are showing “X responses on…”;
– One page is showing two slashes before and after the website field and also showing “X responses on…”;
– Font and spacing are completely different.

It seems like each page/post is grabbing the formatting rule from different sources (which I believe should come from the comments.php of the theme or from the theme-compact) and I have no clue why.

I was actually messing around trying to remove the website field from the comments and got it done (as can be seem in the older posts) by hiding it via css code, but the two latest posts still shows them. I tried reinstalling the theme but didn’t work. Other messings around I did was disable live links in comments editing the functions.php and tried removing the website field by messing around with the comments.php, but changed them back to how they were seeing how it didn’t work.

Can somebody give me a light?
The blog in question is: [NSFW] http://smdc-translations.com/blog/ and it’s NSFW.
If it’s of any help, I’m using the latest version of Deux Milles Douze, which is a child-theme of Twenty Twelve and I’ve already tried reinstalling both themes, but the problem persists.

Thank you.
