Help! How to hide YouTube's original captions while keeping the plugin translation?

Hi everyone, I’m using the Language Reactor plugin on YouTube. Currently, the plugin’s translation seems “locked” with YouTube’s original closed captions (CC).

If I turn off the YouTube CC, the plugin stops working entirely. However, if I leave it on, I end up with 4 lines of subtitles (Original + Translation + Plugin’s double lines), which makes the screen extremely cluttered.

How can I configure the settings to hide the native YouTube CC text and ONLY display the plugin’s translation interface? Thanks for the help!
