And even when I set the season and episode number, the upload button doesn't work at all, see the Javascript error when adding subtitles to upload screen, maybe the javascript error stops the function, which makes the upload button works?

Sorry for the delay, I've tested with attached subtitle, it now can find the season and episode number correctly, and the import button works.

Thank you!
