Problem in selecting a language for subtitles for a movie app

I ran into a problem viewing movies on my Tubi app, using my Macbook Pro. The subtitles in English could not be checked. It would just revert back to the off position. I disabled my VPN and tried again, and I was able to choose the language preference. I then turned my VPN on again and the subtitles remained on. I first thought it had to do with some or one of the extensions I added to the Avast browser, but I was wrong.
