Most of the production codes are numbers we have assigned to the episodes, and they are usually handed out in the order the episodes are broadcast. Many are going to be wrong because Disney shuffles episodes around as they see fit and we stopped having a reliable source for them back around season 2.

If you see a production code in an official source like that picture, then that takes priority over the one we gave it.
