Display arrangement with 3 screens (2x 1080p one 4k)

SUMMARY
Display configuration shows contradictory resolutions for one and the same display setup. Moreover, a restart is needed to make the new display set-up usable - simply logout/login does not solve the issue.

STEPS TO REPRODUCE
1. Connect external display via HDMI, DisplayPort or Thunderbolt, while having internal 4k set to 4k with 2x scaling.
2. Open display configuration 

OBSERVED RESULT
Available resolutions per display do not match the actual per display resolution available, but rather the set resolution divided by the former set scaling.

EXPECTED RESULT
Setting should show actual selected resolution.
