Can you give an example of what your movie naming convention is.
Or run
Post the url of:
ls -al /Path/To/Movies/on/NAS | paste
Personally, I remove any dots resolution size (1080p) etc but add the date.
So. The Green Mile (1999)
There are bulk renamers around.
Once you have renamed them, reselect the source again with the type changed from movies to none, save, then it will clean up the database.
Then scan again, try a few folders first
I also run movies via mkvtoolnix to remove foreign audio or subtitles,
Yeah I did that in the past as well, but since libreelec is smart enough to read the correct names I no longer bothered.
Now al of the sudden this happens. And renaming the movies doesn't look like it is gonna solve this problem.
My library now sais I have 502 murder on flight, otter 501, 500 miles etc I have never even heard of these movies 
ls -la nfs://10.0.1.15/nfs/Media/Movies/ | paste
gives the following error:
ls: nfs://10.0.1.15/nfs/Media/Movies/: No such file or directory
Have you installed any addons recently?
I've found the problem and the solution!
I also have a USB disk attached containing my UHD movies.
Last night I added a folder (skin backup) to that USB disk.
Apparently the files in that folder were mistakenly seen as movies and thus added to my library.
PEBKAC 
@opcxtreme can I mark this tread as "Resolved"? Tnx
I’ll never understand how ...
blanco12 : This is your 4th, really, off-the-chart post you entered on this forum. If this is all you have to offer, then I suggest you simply stop doing what you are doing. It's annoying, and not even remotely funny.
You're welcome to enter into meaningful discussions on LibreELEC and Kodi related topics. So far, you haven't shown any intend to do that.
