Getting a dynamic collection

I have the code snippet from the backend to get a collection of my module item, but it's returning my 8 results instead of the 4 I see in the backend. 

...unless I call a .Distinct(), then I get my 4 back

Any idea what the problem might be?

public void OnRotator_NeedsDataSource(object sender, Telerik.Web.UI.RadListViewNeedDataSourceEventArgs e)
            DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();
            Type rotatorItemType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Rotator.RotatorItem");
            // This is how we get the collection of Rotator Item items
            var items = dynamicModuleManager.GetDataItems(rotatorItemType);
            var data = (from r in items.ToList()
                        select new
                            Image1 = r.GetValue("Image1"),
                            Image2 = r.GetValue("Image2"),
                            SlideUrl = r.GetValue("SlideUrl"),
                            SliderText = r.GetValue("SliderText"),
                            Index = r.GetValue("Index")
            ((RadListView)sender).DataSource = data.Distinct().OrderBy(x => x.Index);
(So I'm transforming the results in order to sort with Linq)...but w/out the last Distinct at the bottom my results are duplicated

Hello Steve,

Most likely you're also getting the master copies of the items, can you please try filtering for the Live status and items that are Visible like this:

var items = dynamicModuleManager.GetDataItems(rotatorItemType).Where(di => di.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live && di.Visible == true);
