Fedora 41 KDE dual screen, individual screen brightness adjust bar on taskbar just dissappeared

My system runs Fedora kde 41, in fact less than a month old.
I have a hdmi monitor attached to the laptop.
Initially, there are 2 individual scroll bar to adjust brightness, one for each screen.
Somehow today i realized there is only 1 scroll bar … which is for the built-in screen, i have no idea why it changes…

Anybody know how to get it back ? or it is another minor bug where there is no way to restrain it ? Thanks.

Try logging out and then logging back in. This feature seems to break randomly.

DDC-based Screen brightness control randomly unavailable in some sessions
