Конструктор сцен javaFX. APP не отвечает, не растет ВПРАВО

Я делаю приложение на JavaFX. Я использую Scene Builder, но у меня проблема с GridPane. Не могли бы вы сказать мне, почему моя GridPane не растет вправо?

Вот скрин моего приложения. Экран моего приложения

и файл FXML:

<BorderPane xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8">
   <center>
