after moving DP4 away

SUMMARY

I got two monitors with different wallpapers and panels.
After one of the latest updates, when logging in after a reboot, both monitors show the primary screen (wallpaper, panel, folder view).
Due to Plasma bug of last year, that frequently shredded my configuration, both screens now are named DP-4 and DP-5 respectively

When I open 
System Settings -> Display and Monitor -> Display Configuration
things get weird:
- the screen shown is DP-4, but clicking on "Identify" shows an overlay saying "DP-5" (s1.png)
- I can move the square symbolizing the screen and move it, and behind it there's another one called DP-5 (s2.png)
- once I hit apply, things are right again -- until the next reboot

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Plasma 5.25 or 5.26?

If it is, please change the status to CONFIRMED when replying, and paste the output of `kscreen-doctor -o` when it's working properly, and then right after you make the bug happen. If not, or if you can't because you no longer use this setup, you can change the status to RESOLVED WORKSFORME. Thanks a lot!
