为什么每当我输入文本区域时，我的所有GUI组件都会移动到JFrame的左上角？

Question

我是Java和Stack Overflow的新手，我正在制作一个注册表单，用于收集用户数据并将其存储在结果窗口中的JLabel中。每个窗口都是在一个单独的类中制作的。我在原始窗口中有一个提交按钮，其代码如下所示，调用生成的窗口，将从文本字段和区域收集的用户数据放入JLabel。

我的问题是：每当我输入我的一个文本区域时，我的所有组件都会移动到窗口的左上角？

以前习惯工作正常。直到我将布局从null更改为spring，然后我停止从JFrame扩展并改为生成JFrame对象。到目前为止，我的另一个班级很好，只是这个给我带来麻烦。

这是用户输入文本的原始窗口的代码：

public class RegistrationForm1{
private JFrame frame;
private JButton submit;
private JLabel fnLabel, lnLabel, dobLabel, phoneLabel, cellLabel, 
ecLabel, ecnLabel, employerLabel, workLabel, alLabel, 
rLabel, ptlLabel, pcpLabel, pcpPhoneLabel;
private JTextArea alBox, rBox; 
private JTextField fnBox, lnBox, dobBox, phoneBox, cellBox, 
ecBox, ecnBox, employerBox, workBox, ptlBox, pcpBox, 
pcpPhoneBox;

public RegistrationForm1(){

    frame = new JFrame("RegistrationForm");
    frame.setLayout(new SpringLayout());
    frame.setSize(500, 570);
    frame.setResizable(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);

}

public void CloseFrame(){
    frame.dispose();
}

public void form1(){
