SfListView items do not update as expected when using LayoutManager

Hello,

We have an issue with the SfListView control when using a LayoutManager and an ObservableCollection as ItemsSource. When removing items from the OC, the rendered items are not updated correctly. In detail:

Expected Behavior

When an item is deleted, it disappears and all following items shift up one position.


Actual Behavior

The deleted item disappears, but the next item gets duplicated, replacing the deleted item in the list (correct behavior) but also staying at the initial position (wrong behavior).

Tested Version

Syncfusion.Xamarin.SfListView 15.4.0.17

Android, iOS, UWP  BAD
