I have a form that set a input verifier to it.

I want when a user type a correct value for a text field and want to go to other text field, a check icon should be display besides of text field. But now in my code, when user type a correct value on first text field an go to other, Two icons displayed together!

public class UserDialog extends JDialog {

JButton cancelBtn, okBtn;
JTextField fNameTf, lNameTf;
JRadioButton maleRb, femaleRb;
ButtonGroup group;
JLabel fNameLbl, fNamePicLbl, lNameLbl, lNamePicLbl, genderLbl, tempBtn, temp3;

    public UserDialog() {
    add(createForm(), BorderLayout.CENTER);
    setDefaultCloseOperation(DISPOSE_ON_CLOSE);
    setLocation(400, 100);
    pack();
    setVisible(true);
}
    public JPanel createForm() {
    JPanel panel = new JPanel();
    ImageIcon image = new ImageIcon("Check.png");

    okBtn = new JButton("Ok");
    cancelBtn = new JButton("Cancel");
    tempBtn = new JLabel();
    fNameLbl = new JLabel("First Name");
    fNamePicLbl = new JLabel(image);
    fNamePicLbl.setVisible(false);
    lNameLbl = new JLabel("Last Name");
    lNamePicLbl = new JLabel(image);
    lNamePicLbl.setVisible(false);
    genderLbl = new JLabel("Gender");

    maleRb = new JRadioButton("Male");
    femaleRb = new JRadioButton("Female");
    temp3 = new JLabel();
    group = new ButtonGroup();
    group.add(maleRb);
    group.add(femaleRb);

    fNameTf = new JTextField(10);
    fNameTf.setName("FnTF");
    fNameTf.setInputVerifier(new MyVerifier(new JComponent[]{maleRb, femaleRb, okBtn}));
    lNameTf = new JTextField(10);
    lNameTf.setName("LnTF");
    lNameTf.setInputVerifier(new MyVerifier(new JComponent[]{maleRb, femaleRb, okBtn}));

    panel.add(fNameLbl);
    panel.add(fNameTf);
    panel.add(fNamePicLbl);
    panel.add(lNameLbl);
    panel.add(lNameTf);
    panel.add(lNamePicLbl);
    panel.add(genderLbl);
    JPanel radioPanel = new JPanel(new FlowLayout(FlowLayout.LEFT));
    radioPanel.add(maleRb);
    radioPanel.add(femaleRb);
    panel.add(radioPanel);
    panel.add(temp3);
    panel.add(okBtn);
    panel.add(cancelBtn);
    panel.add(tempBtn);

    panel.setLayout(new SpringLayout());
    SpringUtilities.makeCompactGrid(panel, 4, 3, 50, 10, 80, 60);
    return panel;
}
    public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            new UserDialog();
        }
    });
}

public class MyVerifier extends InputVerifier {
    private JComponent[] component;

    public MyVerifier(JComponent[] components) {
        component = components;
    }

    @Override
    public boolean verify(JComponent input) {
        String name = input.getName();

        if (name.equals("FnTF")) {
            String text = ((JTextField) input).getText().trim();
            if (text.matches(".*\\d.*") || text.length() == 0) {
                //disable dependent components
                for (JComponent r : component) {
                    r.setEnabled(false);
                }
                return false;
            }
        } else if (name.equals("LnTF")) {
            String text = ((JTextField) input).getText();
            if (text.matches(".*\\d.*") || text.length() == 0) {
                //disable dependent components
                for (JComponent r : component) {
                    r.setEnabled(false);
                }
                return false;
            }
        }
        //enable dependent components
        for (JComponent r : component) {
            r.setEnabled(true);
        }
        fNamePicLbl.setVisible(true);
