Not all files are visible

I’m having theses problems for many weeks now. As far as I know, I’m doing everything allrigh, tho I just cant sync all my (shared) files.

It seemed to be working tonight, but when I took a closer look, it was the same thing again. Not all my movies (all seperate in different folders) are loaded. Not all my series are loaded, and when they are visible: only a few episodes are visible, while I got only complete seasons in my folders. Its just random episodes and movies that are synched on Kodi, sometimes even different ones each time I open up the folder on Kodi.

I reinstalled Kodi on my Pi, I made new shared folders with a new name, made a new Windows user, but nothgins seems to be working.
Please help me out, I really want the old Kodi back on my Pi2
