Files (library source) paths disapear, contents remain…. 17.3

Windows 10 – latest latest updates, June 2017
Kodi 17.3 Final
“Server version: 5.7.18-log MySQL Community Server (GPL)”
Fresh config – no imported stuff except some very mild things in advanced settings.xml
(pastebin regardless: https://pastebin.com/8XMeTC0r )

Video of this, you can clearly see content on my system, you can clearly see no folders / files config in the “videos / files” area.

Pastebin of Debug log, I don’t even care if my passwords are in there at this point.

Also note: manually adding a new files entry for library source, works, then upon close / re-open, it’s missing.
