Redmi note 10 Pro Refresh rate issue

[bladeofmy]

So I got this phone today, after 3 weeks of waiting, I realised that the 120hz does not work. I have turned on the FPS monitoring, ttps://imgur.com/a/drAmt8x , this is what it shows which is absurd. I wanted to ask should I refund this phone or is there a fix for this. The phone seems to go to 120hz only when plugged in, I find this super weird.
