How I turn off subtitles permanently

I am looking to turn off my subtitles permanently, step by step instructions would really help, I have tried changing settings to play only with foreign audio, and a few other things but they still show, I would really rather to not have to turn them off manually all the time.

Go to https://app.plex.tv/desktop/#!/settings/account
Audio & Subtitle Settings
clear the checkbox “Automatically select audio and subtitle tracks”

Ive done that and they still pop up

Which client type?
Which subtitle type? (inspect the Plex Media Info)

Im using the plex app on my smart tv

  • Codec SRT
  • Language English
  • Language Tag en
  • Title English [SDH]
  • Display Title English (SRT)
  • Extended Display Title English [SDH] (SRT)

Which brand of Smart TV?
Which version number of the Plex app?

I finally figured it out thank you for the help
