Buttons move out of window

Hi, in any BaseStoreCancelWindow.java Window, if you add more buttons than Store and Close, the buttons move out of the window. See example here: https://git.gesis.org/stardat/stardat-ddieditor/-/blob/master/src/main/java/org/gesis/stardat/ui/view/questionnaire/ExportQuestionsWindow.java#L71

There are two more buttons added.
