Lost my item sets and key bindings

I seem to have lsot my item sets and key bindings. Only thing I can think of that made this happen is dat I tried to start a game of Legends of Runeterra. It seems it tries to logon with my EUW LoL credentials and then wipe those in the proces. NP. But now I logged in manually again to EUW to play League all but my oldest 4 item sets are gone and my keybindings have reset. Is that a bug??
