Why isnt Properties.Settings.Default being saved?

Question

I wrote this to quickly test

Why arent my settings being saved? The first time i run this i have 3(old)/3(current) elements. The second time i get 3(old)/5(current), third time 5(old)/5(current).

When i close the app the settings completely disappear. Its 3 again when i run it. I made no changes to the app. Why arent my settings being saved

    private void button2_Click(object sender, EventArgs e)
    {
        MyApp.Properties.Settings.Default.Reload();
        var saveDataold = MyApp.Properties.Settings.Default.Context;
        var saveData = MyApp.Properties.Settings.Default.Context;
        saveData["user"] = textBox1.Text;
        saveData["pass"] = textBox2.Text;
        MyApp.Properties.Settings.Default.Save();
    }
