Help me please! I just updated High Sierra and hoped that it will fix my mystery issue but no! 
Background: I have a 2016 MacBook Pro. High Sierra is clean installed and Filevault is enabled. Otherwise everything works fine. I have made hardware test twice - everything's fine.
I have very odd issue. If I run run first aid repair on disk utility my files (library, programs, almost all documents, only a few empty folders, movies, music, photos - all files will disappear, PUF! Gone!
Luckily everything will come back after the booting.
Can someone help me what I should do to fix this annoying issue??
Has anyone else similar issues? Have anyone tested?
I attached a few screenshots. I'm from Finland so the language on finder is a Finnish. I think this is not issue for Mac users foreign and overseas to understand.
