Fix mismatch of individual episode?

Hi,

Is there a way to fix a mismatch of an individual episode of a TV series? Plex has matched both series 4 of NCIS: LA and series 10 of NCIS as NCIS: Los Angeles.

If you go down to the episode in Plex Media Manager, click 'Fix Incorrect Match' and do a custom search for NCIS, nothing is ever returned.

I tried adding the full 'Naval Criminal Investigative Service' to the NCIS file name, and that didn't help.

Thanks.

Alan.
