SUMMARY Switching to "Times" operation mode breaks night color settings and you can't save your new changes anymore or disable it. As a workaround you can remove the [NightColor] section from ~/.config/kwinrc, restart kwin and you'll be able to change settings normally again. STEPS TO REPRODUCE 1. Access Night Color settings, for example by navigating to System Settings > Display and Monitor > Night Color 2. Enable Night Color and change Operation Mode to Times 3. Apply your changes and close the window (important) 4. Access Night Color settings again, make any new changes and try to apply them OBSERVED RESULT The Apply button is disabled and the OK button won't save new changes anymore. EXPECTED RESULT New changes should be able to be applied.

hum, I can't confirm this issue on my system. But I noticed that "Apply" button remains enabled when clicked after I set operation mode to "Times" despite the change is immediately applied after the first click on it. The same occurs if operation mode is already "Times" and I modify any setting (sunrise/sunset times, transition duration, etc). Tested on both Wayland and X11 sessions.
