I started building a new JavaFX project with SceneBuilder. After setting a ListView as navigation (blue background) and a pane inside an hbox (red background) I runned the program and got a white space between listView and Hbox. Why is it there and how can I fix it?

Thats my FMXL-Code:

 <BorderPane fx:id="borderPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="700.0" prefWidth="1100.0" styleClass="parent" stylesheets="@application.css" xmlns="http://javafx.com/javafx/9.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="application.ApplicationController">
 <bottom>
 <HBox maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="30.0" prefWidth="1100.0" BorderPane.alignment="CENTER">
 <children>
 <Pane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="30.0" prefWidth="200.0" style="-fx-background-color: #c30221;" />
 </children>
 </HBox>
 </bottom>
 <left>
 <ListView fx:id="lvNavigation" focusTraversable="false" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="670.0" prefWidth="200.0" stylesheets="@../../bin/application/application.css" BorderPane.alignment="CENTER" />
 </left>
</BorderPane>

And this is my stylesheet:

.parent
 -fx-background-color: #ffffff;
 -fx-padding: 0;
 -fx-margin: 0;


.list-view
 -fx-background-color: #0051a6;


.list-cell
 -fx-background-color: #0051a6;
 -fx-cell-size: 75px;
 -fx-text-fill: white;

Thats my Main-Class:

 BorderPane root = (BorderPane) FXMLLoader.load(getClass().getResource("/fxml/application.fxml"));
 Scene scene = new Scene(root);
 scene.getStylesheets().add(getClass().getResource("/css/stylesheet.css").toExternalForm());
 primaryStage.setScene(scene);
 primaryStage.initStyle(StageStyle.DECORATED);
 primaryStage.setResizable(false);
 primaryStage.setTitle("Sneak/One");
 primaryStage.show();
