When using JButton draw border all buttons disappear

I've been making a program with a GUI using Swing. When I use a JButton with the draw border it makes all other buttons disappear. I have made a program with just the minimal code and the buttons work perfectly fine:

public class ShowError {
  public static void main(String[] args) {
    JFrame _GameWindow = new JFrame("Trivial Pursuit");
    _GameWindow.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    _GameWindow.setSize(800, 650);
    _GameWindow.setResizable(false);
    _GameWindow.setVisible(true);

    JPanel _MainMenu = new JPanel();
    _MainMenu.setLayout(new FlowLayout(FlowLayout.CENTER));
    _GameWindow.add(_MainMenu);

    ImageIcon[] _PlayerButtonImage = new ImageIcon[5];
    for (int i = 2; i < _PlayerButtonImage.length; i++) {
        _PlayerButtonImage[i] = new ImageIcon("Images/" + i + "PlayerButton.png");
    }
    ImageIcon _HowToPlayButtonImage = new ImageIcon("Images/HowToPlayButton.png");

    JButton[] _PlayerButton = new JButton[5];
    for (int i = 2; i < _PlayerButton.length; i++) {
        _PlayerButton[i] = new JButton(_PlayerButtonImage[i]);
        _MainMenu.add(_PlayerButton[i]);
        _PlayerButton[i].setOpaque(true);
        _PlayerButton[i].setPreferredSize(new Dimension(271,123));
        _PlayerButton[i].setContentAreaFilled(true);
        _PlayerButton[i].setBorderPainted(true);
        _PlayerButton[i].setFocusPainted(true);
    }

    JButton _HowToPlayButton = new JButton(_HowToPlayButtonImage);
    _MainMenu.add(_HowToPlayButton);
    _HowToPlayButton.setOpaque(true);
    _HowToPlayButton.setContentAreaFilled(true);
    _HowToPlayButton.setBorderPainted(true);
    _HowToPlayButton.setPreferredSize(new Dimension(271,123));
    _HowToPlayButton.setFocusPainted(true);
  }
}

This code works but when it's in my actual program it doesn't work.

This is from my actual program:

    JButton[] _PlayerButton = new JButton[5];
    for (int i = 2; i < _PlayerButton.length; i++) {
        _PlayerButton[i] = new JButton(_PlayerButtonImage[i]);
        _MainMenu.add(_PlayerButton[i]);
        _PlayerButton[i].setOpaque(true);
        _PlayerButton[i].setPreferredSize(new Dimension(271, 123));
        _PlayerButton[i].setContentAreaFilled(true);
        _PlayerButton[i].setBorderPainted(true);
        _PlayerButton[i].setFocusPainted(true);
    }

    JButton _HowToPlayButton = new JButton(_HowToPlayButtonImage);
    _MainMenu.add(_HowToPlayButton);
    _HowToPlayButton.setOpaque(false);
    _HowToPlayButton.setContentAreaFilled(true);
    _HowToPlayButton.setBorderPainted(false);

If I set the border painted to false everything is fine. When I set it to true everything disappears.

This was actually a really simple fix 

JButton[] _PlayerButton = new JButton[4];
    for (int i = 0; i < _PlayerButton.length; i++) {
        final int FinalI = i;
        _PlayerButton[i] = new JButton(_PlayerButtonImage[i]);
        _MainMenu.add(_PlayerButton[i]);
        _PlayerButton[i].setOpaque(false);
        _PlayerButton[i].setPreferredSize(new Dimension(271, 123));
        _PlayerButton[i].setContentAreaFilled(false);
        _PlayerButton[i].setBorder(BorderFactory.createEmptyBorder());

        _PlayerButton[i].addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                _PlayerButton[FinalI].setBorder(BorderFactory.createLoweredBevelBorder());
            }

            public void mouseExited(java.awt.event.MouseEvent evt) {
                _PlayerButton[FinalI].setBorder(BorderFactory.createEmptyBorder());
            }
        });
    }
