Or the original subtitles for some reason are not present when you turn on closed captions.

Like sometimes the "[Speaking in foreign language] is intentional, there is a plot element mystery because the other characters are not meant to understand it, so we, the audience are not meant to.

Also tangential that gets me, when it says like [Soeaking in Tagalog] or something specific, but less common, then later some character is like, "Si senor" in very obviously Spanish and it says [Speaking in foreign language]. Instead of [Speaking in Spanish].
