Air date correction declined

Hello there, I have yet another problem. For the Pet Alien episode, "The Creature Who Left/It Came from the Fan Club", which is the Season 2 premiere, it claimed that the episode has premiered in 2005. It is actually incorrect, the episode actually premiered on TV in 2006, even the credits for this episode has a 2006 copyright, not a 2005 one. When I tried to fix it by removing the 2005 airdate and keeping the correct 2006 airdate below, the site declined it, even though I explained my reason why I tried to remove it. This needs to be fixed.
