On my Android 12 Motorola phone watching YouTube on Firefox for Android, I am seeing captions/subtitles both on the YouTube screen and separate from the YouTube screen overlaying the page. I do not have a caption add-on. I can turn the YouTube screen captions on and off using YouTube Payback Settings, but I cannot see how or where to turn off the captions overlaying (see screenshot) the YouTube web page/Firefox for Android app. Any help would be appreciated.
