Plasma 6 don't save applications shortcuts

I upgraded my system to plasma 6, and wayland keeps forgetting my configuration that Ctrl+Alt+T should open a terminal (konsole). After every reboot, I need to re-assign this shortcut in the list of applications (that default to nothing). Any idea what is wrong?
