Hi.
I wonder what I am doing wrong because I cannot clone configuration when using wsjtx version 2.1.2 and KDE
similarily when using wsjtx version 2.1.0 and Ubuntu 18.0.4.
I made the first configuration by setting general, rig data and mode FT8 on 40m. Then I tested it and it was OK.
I cloned it and  switched to it and it was OK. I changed mode to FT4 on 40m and it was OK., renamed the first and switched and it is OK.

Now I am  trying to do the same  using wsjtx version 2.1.2 and KDE.
I did as before but both clone and copy saved nothing.
I tried to delete extra configurations but they pop up every time when restarting the progam.
What is wrong or what am I doing wrong?

The last active configuration is OK when restarting the program.

I am running WSJT-X on Linux using a KDE desktop. Why does Menu→Configurations misbehave?

The KDE development team have added code to Qt that tries to automatically add shortcut accelerator keys to all buttons including pop up menu buttons, this interferes with operation of the application (many other Qt applications have similar issues with KDE). Until this is fixed by the KDE team you must disable this misfeature. Edit the file ~/.config/kdeglobals and add a section containing the following:

Thank you for the answer Kari. It seemed to cure the problem. I could not find the cure because it is KDE problem.
