Most of the time Subtitles are Not Available

I'm using Kodi on OSMC and I've added opensubtitles.org
A lot of the time I get "subtitles not available". I seem to be getting a slightly better hit rate for TV vs Movies. Here is the log file:
ilepaxuhew.kodi (paste)

Even though I have the setting to store the subtitles in the same folder as the video, when I look in the folder for the ones that *do* work, there is no subtitle file.
All the videos are on a directory on the network that is shared, and mounted in OSMC.
