I think your issue is caused inside the areaSeries with Background=”Red”. The DataPointStyle actually has the background.
Remove that temporarily and if it solves your problem then I think you want to access the DataPointStyle of your area series to set the background.

Edit: Removed my xaml example, as a direct setting in place of styles does work.
