CollectionView: Can't drag first item to the second place

[AmirImam]

Hi
I don't know if this is a bug or not, but I think it is a problem.
I want to drag & drop items in a CollectionView. When I drag the first item and try to drop it on second place it doesn't work, and it makes the CollectionView scroll so fast. I don't know if this explanation is enough or not, but I attached an image that describes the situation

Note that the item in the second place doesn't move to let me drop the dragged item, and it suddenly keep scrolling
My XAML:

 <sho:CollectionView x:Name="Collector"
                            ItemHeight="140" 
                            VerticalOptions="FillAndExpand"  
                            ItemSpacing="20"
                            EnableDragAndDrop="True" 
                            DragAndDropStartedCommand="{Binding DragStartedCommand}"
                            CurrentIndex="{Binding Order}"
                            ItemsSource="{Binding Collection}">
            <sho:CollectionView.ItemTemplate>
                <DataTemplate>
                    <sho:DraggableViewCell x:Name="DraggableViewCell">
                        <ContentView>
                            <StackLayout>
                                
                            <StackLayout Orientation="Horizontal">
                                <Image Source="{Binding Thumbnail}" 
                                       Aspect="Fill" 
                                       WidthRequest="50" HeightRequest="50"
                                       VerticalOptions="Center"
                                       HorizontalOptions="Center"/>
                                <StackLayout>
                                    <Label Text="{Binding OrderIndex}" />
                                    <Label Text="{Binding Title}" FontSize="Large" TextColor="Black" />
                                    <Label Text="{Binding Description}" FontSize="Small" TextColor="Gray" />
                                </StackLayout>
                            </StackLayout>
                                <BoxView HeightRequest="1" BackgroundColor="Gray" />
                            </StackLayout>
                        </ContentView>
                    </sho:DraggableViewCell>
                </DataTemplate>
            </sho:CollectionView.ItemTemplate>
        </sho:CollectionView>
