Subtitle won't work after update to 1.0.2.2413

Subtitle won’t work on newest version of PlexServer for Windows with recently added movie.
Only works with already added movie on old version.
What happen??
A lot of people asked about it, but never answered.
Please support this problem, Plex!
I am a PlexPass user for a lifetime.

Oh… I just moved files to other folder, refresh the folder, and restore files to original folder, refresh again in Plex.
It resolved the problem.
