Cannot set a ListView ItemsSource to a custom object list

Question

I'm trying to create a ListView of recent files that the user has opened in a program. I have used a custom object called GameFileData that stores 3 variables, Path (string), Name (string) and LastEdited (DateTime). These details are stored in a List object.

Here's the XAML for the ListView

<ListView x:Name="LvRecents" SelectionMode="Single" Margin="5,41,10,35">
    <ListView.View>
        <GridView>
            <GridViewColumn x:Name="ColName" Header="Name" DisplayMemberBinding="{Binding Name}"/>
            <GridViewColumn x:Name="ColLastEdited" Header="Last Edited" DisplayMemberBinding="{Binding LastEdited}"/>
        </GridView>
    </ListView.View>
</ListView>

In code-behind, I have a method that executes when the window loads:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    LvRecents.Items.Clear();
    List<GameFileData> gfd = Saves.GetRecents();
    LvRecents.ItemsSource = gfd;
}

When I run the code with two items in the list, the ListView correctly displays two selectable items, but they have no contents:

I have also tried the same with the Path variable instead of the LastEdited, thinking maybe it's to do with the strange data structure, but I get the same result

Edit: As requested, the GameFileData class:

public class GameFileData
{
    public string Path;
    public string Name;
    public DateTime LastEdited;

    public GameFileData(string path, string name, DateTime lastEdited)
    {
        Path = path;
        Name = name;
        LastEdited = lastEdited;
    }
}

Breakpoints have determined that GetRecents() returns the list correctly
