Two different Plex servers on same data - one sees episodes, other doesn't

The second scan of the Plex Dance is still running, but already things are looking much better. I left out the REPLAY files when copying the data back (I think they’d get numbered somewhere among the specials; once I figure that out I can name them properly and move them to the Season 0 folder), and also the Specials and Season KTMA folders (the contents of which, again, probably belong somewhere in Season 0). But it’s showing Seasons 0-13 as expected, and at least at a glance, it’s showing the correct number of episodes for each.
