Most of the sites label the episodes incorrectly and mix up the episodes. That's why there are lots of confusion regarding what's what.

Anyway, since you're talking about 6 specials in the second season (New). That's most likely the unaired episodes that were released together with the BD/DVDs thus not labeled as "specials" in the wiki as they're not.

Most sites doesn't have those as they only uploaded the tv released episodes and didn't bother to update it with the episodes that have the unaired scenes incorporated in it.
