How to change default of a soundtrack/language with PotPlayer

[pintree3]

I stopped using GOM player about a year ago, VLC is still loved but it doesn't remember last playback position hence PotPlayer.
I have a TV series whereby the default sound is Russian--audio stream 1. I would like to automatically go on Audio Stream 2--the original English Language.
Now I have to do it manually each and every time. Does anyone know how I can have it do this on its own?
There is a place where you can input preferred language and I have put that into English but it seems to have done nothing.

Preferences > Audio > Language/sync/other > Preferred languages: en eng english

Sometime the audio language is missing in video, so it doesn't work, you can edit video, or use option "Preferred stream: 2". You will have to change it back later though.

Thank you Dreamer. Your first suggestion, 'language' is what I had and hasn't worked. Your 2nd suggestion 'stream 2' for some reason was greyed out, hence could not be altered. However, I noticed that if you switch from preferred language to preferred stream on the top then the choice becomes available. And it works.
Thank you
