Why does my label not have any text in it? C# WinForms

Question

I have the following subroutine to create a label, located in form 1:

private void MakeLabelForGameStyle()
{
    Label SelectedMode = new Label();
    SelectedMode.Text = form2obj.GameStyle;
    SelectedMode.Location = new Point(507, 92);
    SelectedMode.AutoSize = true;
    SelectedMode.Font = new Font("Calibri", 12);

    Controls.Add(SelectedMode);
}

In form 2, the relevant code to determine 'GameStyle' is as follows:

private string gameStyle;

private void button3_Click(object sender, EventArgs e)
{
    gameStyle = "Best Of 3";
    Close();
}
private void button4_Click(object sender, EventArgs e)
{
    gameStyle = "Best of 5";
    Close();
}
public string GameStyle
{
    get { return gameStyle; }
}

But when I run the program, the label is blank after clicking either of the buttons.
