Are you using a custom format?
If you write your own custom format, then you will want to rely on the built-in bindings such as {plex.name}, {sxe}, {s00e00}, {t}, etc as much as possible. Those are multi-episode aware / special-episode aware / etc. {s} and {e} are always a single number. {es} is the list of episode numbers. S01E02-03 is a clear multi-episode pattern and should work out-of-the-box, assuming that your custom format is capable of formatting multi-episode information into multi-episode file names:
Code: Select all
$ filebot -rename *.mp4 --db TheTVDB -non-strict --format "{plex.name}" --action TEST --log INFO
