Cannot adjust color profile of the second (external) monitor

[Benoe]

In gnome settings at color management when I try to apply a profile to my external monitor, the internal monitor's colors are changing. No change on the external. A week ago it was working correctly.

I can also see some flickering on the internal monitor, when night mode is on, and the color scheme is changing
