SplitView not opening when using DeviceFamily views

Question

I am currently working on a UWP implementing a SplitView so I can use a hamburger menu. I am also working with the DeviceFamily views so as to create tailored experiences for desktop and mobile. However, I cannot get the split view to open on either device. I can set it as open on the phone then use the button to close it but then it will not reopen.

Here is the XAML for the desktop (it is only rough right now):

And the code that is behind the page, simple though it is:

using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;

using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;

        }

    }
