In movie, translation subtitles missing

I am finding older movies not having translation subtitles when people are speaking a foreign language, like in the beginning of The Hunt for Red October or Stargate. Watching the movie on the the physical copy of Stargate, when they are speaking Egyptian, English subtitles come up translating what they are saying. On my digital copy, I have to have subtitles on all the time in order to see the translation, which sucks because I don’t need subtitles the rest of the movie, just when they are speaking Egyptian. My theory is that there was some sort of trigger on the physical copy that activates the subtitles at that point that is missing from the digital copy. Is there a way to fix or get around this? Or am I just stuck reading subtitles the entirety of the movies if I want to know what people are saying in the foreign language?
