    Default buttons randomly show up in program

    Hey guys,
    So I've designed a simple converter that has 4 buttons and 5 labels on the main frame which invoke a series of converters. The weird thing is that after I export the classes to a .jar file and run the jar the labels and buttons will randomly not load or won't load until I mouse over them and other times it will load fine. I'm wondering if I have something in the wrong location on the main class. Here is the main frame code.

    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;

    import javax.swing.*;

    import converters.FrameClass;
    import converters.KGConverterClass;
    import converters.MilesFeet;
    import converters.YardstoMeters;

    public class FirstFrame {



    //ActionListener for the yards to Meters
    static class Action4 implements ActionListener{
    public void actionPerformed (ActionEvent e){
    YardstoMeters open = new YardstoMeters();
    open.Converter4();
    }
    }

    //ActionListener for the miles to feet
    static class Action3 implements ActionListener{
    public void actionPerformed (ActionEvent e){
    MilesFeet open = new MilesFeet();
    open.Converter3();
    }
    }
    //ActionListener for the FT to CM converter
    static class Action implements ActionListener{
    public void actionPerformed (ActionEvent e){
    FrameClass open = new FrameClass();
    open.Converter1();
    }
    }
    //ActionListener for the KG to LB converter
    static class Action2 implements ActionListener{
    public void actionPerformed (ActionEvent e){
    KGConverterClass open = new KGConverterClass();
    open.Converter2();
    }

    }
    //ActionListener that EXITS the program
    static class ActionExit implements ActionListener{
    public void actionPerformed (ActionEvent e){
    System.exit(0);
    }
    }

    public static void main(String[] args) {


    //frame and menu bar
    JFrame frame = new JFrame("Lane's Converter");
    frame.setVisible(true);
    frame.setSize(400,350);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);

    JMenuBar mb = new JMenuBar();
    JMenu file = new JMenu("File");
    mb.add(file);
    JMenu about = new JMenu("About");
    mb.add(about);
    JMenuItem exit = new JMenuItem("Exit");
    exit.addActionListener(new ActionExit());
    file.add(exit);
    frame.setJMenuBar(mb);

    JPanel panel = new JPanel();
    panel.setLayout(null);
    frame.add(panel);



    JLabel mainlabel = new JLabel("Choose a Converter");
    mainlabel.setBounds(120,10,200,20);
    panel.add(mainlabel);



    //Buttons and Labels for the main frame
    JButton button1 = new JButton("Run");
    button1.addActionListener(new Action());
    button1.setBounds(200,50,60,23);
    panel.add(button1);
    JLabel l1 = new JLabel("FT to CM");
    l1.setBounds(90,50,100,23);
    panel.add(l1);

    JButton button2 = new JButton("Run");
    button2.addActionListener(new Action2());
    button2.setBounds(200,100,60,23);
    button2.setLayout(null);
    panel.add(button2);
    JLabel l2 = new JLabel("KG to LB");
    l2.setBounds(90,100,100,23);
    panel.add(l2);

    JButton button3 = new JButton("Run");
    button3.addActionListener(new Action3());
    button3.setBounds(200,150,60,23);
    button3.setLayout(null);
    panel.add(button3);
    JLabel l3 = new JLabel("Miles to Feet");
    l3.setBounds(90,150,120,23);
    panel.add(l3);

    JButton button4 = new JButton("Run");
    button4.addActionListener(new Action4());
    button4.setBounds(200,200,60,23);
    button4.setLayout(null);
    panel.add(button4);
    JLabel l4 = new JLabel("Yards to Meters");
    l4.setBounds(90,200,150,23);
    panel.add(l4);
