Bit hard to keep it to a short title!
When no airdates are available for a show where episodes have been added and the show's status is set to ended, it should list the highest numbered episode in the Previous Episodes section.
Two examples of this are Westwood Park and Big Mouth Do Do.
At a quick glance, it appears like no episodes have been added as the Previous Episodes section shows "No results found."
However with both of these shows that I've created, episodes have been added, just no airdates are available.
