I just switched from the Kodi default skin to the OSMC skin and I noticed something weird.
If I navigate to a movie → Information → More…, then I see all audio and subtitle tracks of the movie.
Now if I start a movie → stop it → go back at least one menu level → navigate to the movie again → Information → More…, then there is only the audio track listed, which I had selected when stopping the movie. And no matter which subtitle track I had selected, subtitle tracks aren’t listed anymore in the “Info->More” menu after playback.

This doesn’t affect playback at all, but I wanted to tell you.
Before first playback:
After playback:
