Explanation of figcaptions on Journal de Quebec

Well, when i read Shameem's issues list, i've rechecked my template for this domain and found something interesting. I was absolutely sure that i spend a lot of time to make correct figcaptions on this site.

But if i open saved page in my editor, something went wrong.

Here (sorry for the quality, on my computer all was good, hmm) you can see that preview diffs changes, but i havent change the rules and didnt click to "Reload". Proofs:

On another page i've checked i've seen same situation:

You can check it by yourself, just look at this template saved pages. Pages which contain captions lose 'em without any actions from my side.

Please, could you explain me, how can this happen?

Previous version in console shows that all was working correct.

I think, IV engine mechanics was changed during contest and i'm ready to fix this problem after announcing winners.
