@bryandoyle It actually does work when you select the matches, just doesn't change the Title or Episode titles to english.
I'm able to get an english show description, but can't get the Title or Episode Titles to the english version.
I use a small test video file and put them in my test local import directory as;
TV\The Night Manager (2016)\Season 01\The Night Manager (2016) - S01E01 - Episode 1 (2016-02-21).mp4
TV\The Night Manager (2016)\Season 01\The Night Manager (2016) - S01E02 - Episode 2 (2016-02-28).mp4
TV\The Night Manager (2016)\Season 01\The Night Manager (2016) - S01E03 - Episode 3 (2016-03-06).mp4
TV\The Night Manager (2016)\Season 01\The Night Manager (2016) - S01E04 - Episode 4 (2016-03-13).mp4
TV\The Night Manager (2016)\Season 01\The Night Manager (2016) - S01E05 - Episode 5 (2016-03-20).mp4

@tmm1 I tested fix incorrect match with the three tms id's and they give an english show description but all keep the Title: Éjszakai Szolgálat and the Episode titles: Folge 1,2,3,4,5 and 6. Appears to either be selecting the wrong language or not updating the Title and Episode titles with what is returned. I ran across this before with a show I recorded and you told me to delete something, but forget what it was.
