Hello. When the system starts, on the logon screen (breeze, plasma 6) the buttons (reboot, shutdown, sleep) use an English language that is different from the system one, but date and time correctly. Moreover, on the lockscreen and when you turn it off, everything is fine, the correct language is used. The language settings in the system are correct. This behavior began after some update.
