Debug log?  

 Local movie database issue.
Log file: http://ix.io/1cd8

Just tested it again with tonight #0603. The same issue. I checked it on 2 separate installations. Once the database from the past April goes through new Kodi version it gets upgraded with no way back. I tried to roll back to April release, delete the storage location and recreate the database. The same thing. Around 20% of the movies does not get recognized anymore. I made quick fresh SD install with LibreELEC-RPi2.arm-8.2.5.img.gz image and applied latest #0602 build. Works OK with all recognized.

It's the old upgraded database that gets corrupted with some titles locked out. I don't really want to go through recreation of everything from scratch. I have multiple installations.

Update:
First log was from folder scan.
Second log from trying to display "Info"

I'm not sure what the fundamental issue is - can you provide details of a movie that isn't recognised, maybe it's an odd naming convention?

Is this failure to recognise a movie happening during a library scan (adding a new movie), or during a database upgrade (as happened, possibly coincidentally, in #0602)?

Build #0602 included the first video database upgrade (v110) of this year, but if you're saying the problem is present in a build from April then I guess we can discount the db upgrade. The reason I asked for your logs was because I suspected a database error, but that looks OK - no errors.

Without knowing entirely what the problem is, it might be best if you can identify the first build with the problem.  

After database upgrade it won't recognize some movies even after reversing back to previous builds. The same movies will work just fine when scanned with new build of Kodi using fresh copy of official Kodi 17 with upgrade to #0602.

The old upgraded database flashes file name quickly during the scan and Kodi moves to the next file. I don't think this it's the naming. It works OK with official Kodi 17 even after upgrade to #0602.
If there is an issue with database upgrade since #0602 other people should see it shortly. Movies scanned by the previous version of Kodi are fine after upgrade. Only the ones scanned into #0602 are showing problem. If you change filename slightly on the existing movie and allow #0602 to re-scan it again it will produce this issue. One of them is Gringo.2018.1080p.BluRay.x264.DTS-HD.MA.5.1-FGT.mkv. Another is Tomb Raider and others but not all.

The upgrade of database was quick and without any errors.

I can't identify the first build. Everything worked until I upgraded today to #0602. After upgrade to #0602 some new movies scanned into #0602 were not recognized. They were still not recognized even if I reversed the upgrade to previously used April builds. I removed the source location and deleted associated records. After adding it back to #0602 I ended up with more unrecognized movies. The same thing happened with previously working build #0407. After database upgrade the #0407 is not scanning the movies that worked before the upgrade.

Can anybody check it. Just change something in the filename and rescan with #0602 or grater. It needs to be older database. Once you rename the filename and turn it into unrecognized press "I" for info.

Maybe it's just me or something on my system. It happened before
