✅ Navigating my window only display the next page's name instead of its contents

I hope you're all well. I got stuck on a WPF XAML problem where my pages wouldn't navigate and after a while of research, I still can't seem to figure it out. Basically, I have my Main Window page which has a button event that changes the page's content using the frame to the content of the new page ("OrdersPage.xaml") I've written my MainWindow XAML like so:

<Controls:MetroWindow x:Class="DatabaseTest.MainWindow"
        xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
WindowTitleBrush="Gray" GlowBrush="Black"
        WindowStartupLocation="CenterScreen"
        mc:Ignorable="d">
    <Grid Background="#312F2F">
        <Frame x:Name="mainFrame"/>
...

<Controls:MetroWindow x:Class="DatabaseTest.MainWindow"
        xmlns:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
WindowTitleBrush="Gray" GlowBrush="Black"
        WindowStartupLocation="CenterScreen"
        mc:Ignorable="d">
    <Grid Background="#312F2F">
        <Frame x:Name="mainFrame"/>
...

My OrdersPage looks like this:

<Controls:MetroWindow x:Class="DatabaseTest.OrdersPage"
        xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DatabaseTest"
        mc:Ignorable="d"
        Title="OrdersPage" Height="450" Width="800">
    <Grid>
        <TextBlock Text="Hello"></TextBlock>
    </Grid>
...

<Controls:MetroWindow x:Class="DatabaseTest.OrdersPage"
        xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:DatabaseTest"
        mc:Ignorable="d"
        Title="OrdersPage" Height="450" Width="800">
    <Grid>
        <TextBlock Text="Hello"></TextBlock>
    </Grid>
...

And in the C# behind this class is a method that handles a button press which looks like this:

    public partial class MainWindow
    {
                 public static NavigationService NavigationService => ((MainWindow)Application.Current.MainWindow).mainFrame.NavigationService;

...

        private void SendCustomerBtn_Click(object sender, RoutedEventArgs e)
        {
            if(parseCustomer is not null)
            {
                MainWindow.NavigationService.Navigate("OrdersPage.xaml");
            }
        }

    public partial class MainWindow
    {
                 public static NavigationService NavigationService => ((MainWindow)Application.Current.MainWindow).mainFrame.NavigationService;

...

        private void SendCustomerBtn_Click(object sender, RoutedEventArgs e)
        {
            if(parseCustomer is not null)
            {
                MainWindow.NavigationService.Navigate("OrdersPage.xaml");
            }
        }

From what I wrote and reading off of other articles I believe that this is written correctly, however when I run my program and click on the button it displays in the top left-corner, "OrdersPage.xaml" as a small black text. (Image here): I am really confused on why this is happening and would appreciate any help.
