Disable English Subs Until Manually Re-Enabled

Whenever starting a show, I noticed that English subtitles for the show are enabled along with the subtitles in the language you’re learning. I disabled the English subtitles because, in my opinion, this defeats the purpose of immersing myself in the language. However, everytime I leave the show I’m watching, it reenables the English subtitles. This is incredibly annoying and I can’t find any way to permanently disable English subtitles. I do not want to constantly have to disable these subs every single time I load up a new video.
