Try the Plex Dance with the episode.
When you finish step 4, the episode should not appear on the server (as if it was never there).
When you finish with step 6, it should be listed correctly, with just one entry in Media Info.
If that does not work, run DBRepair for Plex Media Server. It will check the database for structural issues and attempt to repair any it finds. It also optimizes the database in the process.
Use STOP, then AUTO, which combines several of the individual steps. If everything is OK you can START and EXIT.
If it finds problems it cannot correct, then report back and include the output.
