Nevermind. I didn't see the "sync settings" option... I do think this should be more explicit than a sync button and a pretty obscure text where numlock is mentioned. In French, it is mentioned at the 5th place between Plasma theme and cursors...
I think the real issue is that settings should be synced by default on single-user systems because nobody can ever find this feature. :)
