Display Configurations (1) - two displays - first selected

SUMMARY
I have multi-monitors configuration. There are two displays connected via HDMI. First is main monitor (always enabled), and second projector (periodically enabled), which I enable only to watch the movie and just disable when I finish. The issue is that, when I disable projector then picture on view correctly changes, so disabled display disappears, and only main monitor is visible, but the the setting below are related with disabled one (check attached pictures). I mean I can see main monitor on view and settings for projector. This is happen just because after disabling previous (enabled) display isn't highlighted/selected.

Preconditions:
Multi-monitors configuration. At least 2 displays.

STEPS TO REPRODUCE
1. If second display is not enabled, then please enable it.
2. Press Apply, and OK, and close System Settings.
3. Open System Settings -> Display Configuration.
4. Switch to second display by clicking into picture on view.
5. Uncheck "Enabled" option
6. Press Apply.


OBSERVED RESULT
The settings below are related with disable display.

EXPECTED RESULT
The settings should be switched to currently enabled display.
