Visual Studio 2017 15.9.7

I've got a KeyNotFoundException when im updating the ItemSource of a SfRotator in UWP.


   at System.ThrowHelper.ThrowKeyNotFoundException()
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at Syncfusion.UI.Xaml.Rotator.SfRotator.ItemsCollectionChanged()
   at Syncfusion.UI.Xaml.Rotator.SfRotator.OnItemsChanged(Object e)
   at Xamarin.Forms.Platform.UWP.TaskExtensions.<>c.<WatchForError>b__2_1(Object e)
   at System.Threading.WinRTSynchronizationContextBase.Invoker.InvokeCore()

The iOS and Android version works fine. 

I have attached an example solution to recreate the problem.
