Wikipedia and Imbd are not reliable sources plus they're probably from the US release dates if there were any as many episodes from season 6 were held over until Season 7 in the US. Besides sites like Wikipedia can be edited and change by anyone and you wouldn't notice
I don't know the exact reason and I'll have to look into that but they were held over that's why, for example, in the episode The Magic Baby it shows the new opening with Kimi even though Kimi wasn't there because it was a season 6 episode that appeared in the US in season 7
Like I said I don't know the reason and I don't think it was ever figured out why but those episodes got held back besides most reliable sources have the episodes in the order they are now so how they currently are, are not wrong and I would refrain from changing them.
Hello JustMeJordanW I will like to apologize for the comment I made replying to your comment on the Vacation (episode) it was A complete misunderstanding and I'm sorry I just did not notice what the trivia side about the Carmichel's ware abouts and I did not see you were asking a question before ranting so I'm sorry for that comment and when i saw what the trivia side about them and what it side so i decided to fix it and again i do apologies it was a complete misunderstanding.
