WPF loading page into frame but missing button?

Question

Hi everyone,

I'm creating a very basic application that lets you flick between pages using buttons. It starts off by loading each page onto a frame, however it only seems to be loading the image and not the buttons?

Here is my MainWindow.xaml.cs that controls the frame:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        Loaded += MyWindow_Loaded;
    }

    public void MyWindow_Loaded(object sender, RoutedEventArgs e)
    {
        FrameElement.NavigationService.Navigate(new Home());


    }

}

After that, it navigates you to a page called "Home" and displays two buttons. The buttons appear in the preview for the page but not when I click Run. Any advice?
