After update to SP Page Builder Pro 4.0.8: Screen-size dependent hidden widgets always visible

After the latest update od SP Page Builder Pro, all widgets are displayed, even those that should be hidden, e.g. on desktop, tablet or mobile. This seems to be related to the fact that the settings are somehow duplicated, once they exist in system language (in my case German) and once they exist in English. Only if I also activate the English slider button, the widget desappears.
