nvidia-settings PowerMizer Settings disappear

[0pLuS0]

Hi,

My Specs:

Arch Linux
niri 25.11-2
kernel: 6.18.19-1-lts
nvidia open 580.105.08

When I first open nvidia-settings and click on PowerMizer in the left pane, at the bottom of the PowerMizer options, the PowerMizer Settings where you can set the Preferred Mode, this section disappears, as soon as I click PowerMizer in the left pane, it only appears for a brief second.

Is anyone else using Nvidia noticing the same thing, and is there a way to keep it there?

Here's a screen shot showing it gone at the bottom.

THANKS

P.S. After posting this, 590x drivers fix this....
