vaadin проблемы с полосой прокрутки в модальном окне

[Vasypu2019]

проблема такая у меня несколько классов которые наследуются от класса Window, из них я делаю модальные окна и у одного окна проблема с полосой прокрутки, она пропадает как только я нажимаю на содержимое окна, у остальных окон такого нет, что это может быть?

public class UserEditWindow extends Window {
