Season 2 has 20 episodes, all aired. On the show's page it said "Previous episode 2x01", instead of 2x20 https://i.imgur.com/aKSfZlT.png
Now the new season added but the order of previous episodes is still messed up.
I suppose that's because episode 2x01 has airtime, and the rest don't, but shouldn't episode numbers have a preference above everything else?
Probably for the same reason the show info box doesn't say "Running;returning"
