Subtitle offset not functioning properly on nVidia Shield

Edit; I just figured out that if I adjust the offset, then exit the episode and start watching it again, it will update the subtitle to the correct offset I've picked. Quite annoying, anyone know of a fix?

Does anyone else have the issue with the nvidia shield (not pro version) that the subtitle offset option is there, and I can adjust the offset by plus or minus, but it doesn't actually work?

I can have a subtitle offset by a second, and then I set the offset to -7000ms, and it's still offset by a second.

Anyone else have this issue and know of a solution? Both plex and the Shield are updated to the newest versions.
