Bug below, but I think it is saving the script, but not showing. So now I fear that KDE will run my script multiple times every log in, which is not good. How do I remove the duplicate entries for the login script, when I can't even see them in the UI?

---

SUMMARY
When setting a login script to run in the system settings, it does not show again after I close the window.

STEPS TO REPRODUCE
1. Add login script to the autostart system settings.
2. Close the settings window.
3. Open the settings window again.

OBSERVED RESULT
No autostart scripts are shown.

EXPECTED RESULT
Previously selected autostart script is shown.

Please file a bug report on https://bugs.kde.org, the forum is the wrong place to report this

Please see why I posted here in my other thread.

Do you have any idea how to remove the duplicate entries through the command line, as the UI is not showing them?

I had the same bug. For me, ~/.config/autostart was not a directory but a file. I deleted the file and recreated the autostart dir. I restarted just to be sure and I could add scripts and applications again.
