Just trying out Jellyfin for the first time. I'm also just trying out media server software for the first time, having downloaded Emby 2 weeks ago so forgive if I'm misunderstanding some fundamental concepts.

I have a series on my hard drive that has been incorrectly identified as something else, the Title is wrong, the posters are wrong, the casting information is wrong and I'd hazard a guess the subs are probably wrong too. That's fine, Emby actually got this particular series wrong as well. The difference here though, is I can't figure out what to do about it. I've seen lots of forum posts saying you can enter an imdb ID number but this is a problem because that only seems to be possible for individual episodes, not the whole series, and in any case, it doesn't appear to DO anything when I apply to any one given episode. More frustrating still, each episode in the series has somehow taken the name of the series as its episode name so they all have the same name and you can't tell which episode is which.

How do I remove the incorrect identificaiton and replace it with a manually selected correct ID? Also, importantly, will supplying a correct IMDB number or whatever else it is I need to do to correct this misidentification, cause the correct subs to be downloaded?
