On the BluRay DVD for Spectre, the default language was Spanish. If I went to settings, changed the audio to English, and then scrolled down to Captions, the audio setting disappeared and, invisibly, changed back to Spanish. It turned out that you had to hit Enter after setting it and then it would make the change and automatically go down to captions. I don’t know if this helps, but it had me scratching my head for a little while.
