Movies/series not added/added with wron title name to Kodi Library

Hello

I’m using Kodi for few days now, and i still didn’t fixed one of my problems - not all movies/series has been added from HDD to my library.

I think in most cases problem was that Kodi wasn’t able to find informations about movies in internet source - problem with file/folder names etc.

How can i help Kodi to find correct informations…for example type movie name?

What if Kodi incorrectly described some of my movies ? For example he described Avengers 2 as Avenger 1…is there any tool i could use to fix all problems with my library manualy?

I use nfo files or just renaming the according too how kodi wants…
