Error message when binding to an observable collection

[ICS]

I am able to manually add data to an observable collection of strings and it shows up in the combo box with no issues. However, when using an ObservableCollection of a custom model, it gives me this error. Any ideas why?

   at Windows.UI.Xaml.Controls.TextBox.put_SelectedText(String value)

   at Syncfusion.XForms.UWP.ComboBox.SfComboBox.OnComboBoxSourceChanged(DependencyObject obj, DependencyPropertyChangedEventArgs args)

   at Xamarin.Forms.Platform.UWP.TaskExtensions.<>c.<WatchForError>b__2_1(Object e)

   at System.Threading.WinRTSynchronizationContextBase.Invoker.InvokeCore()

   at Windows.ApplicationModel.Core.UnhandledError.Propagate()

   at Microsoft.AppCenter.Utils.ApplicationLifecycleHelper.<.ctor>b__17_1(Object sender, UnhandledErrorDetectedEventArgs eventArgs)

--- End of stack trace from previous location where exception was thrown ---

   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

   at Microsoft.AppCenter.Utils.ApplicationLifecycleHelper.<.ctor>b__17_1(Object sender, UnhandledErrorDetectedEventArgs eventArgs)
