Hello,
after I installed WPML and changed the language from German to another language, the layout was moved and a widget was inserted.
If I switch back to German, everything is fine again.
To assist you in the best possible manner, I kindly ask that you please provide me temporary wp-admin info (wp-admin URL, username, password) and screenshots that illustrate the problem to the Private Content area, this will allow me to thoroughly investigate and address your concerns more efficiently.
