All the sources I am finding are the airdate order, which is what we use as the primary order. The production order is entered as an episode group. Nothing needs to be changed.

Season 1's production order is not correct here. The correct order was featured on the DVD set. See also the first line of the Production paragraph at wikipedia Male Unbonding

I understand that, however, the episode order on the season page is by airdate, not production. The episode order that matters the most to us is the airdate order, because that's how the episodes were originally released on television. Episode groups were created to have other orders, such as the production or DVD order. For Seinfeld, the production order is here.

I understand, however I am not seeing a way to re-order the season 1 production order page. Does it not use the episode number to sort? I see all of the production codes are correct in the episodes (with Male Unbonding listed as 102), but that is not how it is sorting on the production order page.

Ah, I see what you mean. I updated the production order for season 1.

Awesome! Thank you!
