New movies not recognized

[dcruff 15]

I have a large library of over 5,000 movies on an Unraid Server.  Everything runs smoothly for the most part, but in a recent addition of movies, I noticed that one of my movies (Future, The (2011)) was not being recognized and didn't show up in the library.  I tried moving it's folder to another recognized library folder, but it still did not show up.  Finally, I changed the name to something unrelated, and the item showed up in my library with the new wrong name.  I then edited used the 'Identify' to accurately pull up the correct metadata.  Then I went back to the storage location, renamed the folder and movie back to the correct title and did a rescan.  Now the data is correct and the item is in the library where it should be.
This caused me to think that I may have other movies that are not showing up in the library, as I don't always go back and check to see if a newly added movie actually made it.
Is there some report or simple way to audit the library to see if all of the movies in the file system are actually recognized and added to the library?

Movie Naming

I use this folder nameing and file nameing

Folder : 300 (2007) {TmdbId-1271}

File : 300 (2007) {TmdbId-1271}.mvk

Adding that TmdbId really helps Emby to find the right metadata.

And changing the name to (Future, The (2011)) does not help. 

The movie is named (The Future (2011))

Guessing its this movie The Future (2011) — The Movie Database (TMDB)
