Hello,
I'm a new KDE user and I have a little issue on my machine...
I use Debian 9 64-bits with KDE Plasma 5.8.6.
The issue is that I set the shortcut (right click on applications launcher,Application launcher settings,Keyboard shortcut) to alt+f1 to use meta key to open the launcher.
But after each reboot the key is reset to "None" and I have to set it every time...

Do you have an idea on what could cause this issue ?

Thanks !
