In The Office (2005) some episode are out of place, as well as all 2 part episodes are combined for some reason. I have no idea why this is needed but if there's some logistical reason I get it.
In The Office: Superfan (2020) many episodes from seasons like 3 and 4 are straight up missing. If anyone is looking at it and wondering why season 9 is missing that is because Peacock hasn't released it fyi.
