same here:
After initial login, i have to sliders for internal screen (laptop) and
external (usb-c)
Let the machine sleep, and afterwards we have 2 sliders for usb-c connected
screen.

And, the display brightness is way off:
On the monitor-controls, the setting is: brightness: 30
Plasma shows initially: built-in: 20%, HP/usb-c: 50%

Overall brightness is as i want it.
After sleep, the external monitor is way too dark, i even need to put it to
over 70% to get a similar brightness as before.

This is just awful... how can i stop plasma from handling the brightness? (any
off-switch somewhere?)
