Commented Unassigned: DoubleUpDown Dependency Property Already Registered [22247]

I am getting the following Xaml designer error when I use two different types of UpDown controls in the same document (In my case I have several IntegerUpDown controls and a DoubleUpDown). It seems that the dependency property is being registered multiple times, though it appears to be set up correctly as a static property in CommonNumericUpDown<T>. If I get rid of the DoubleUpDown control, the error goes away, but if I leave the DoubleUpDown and get rid of the IntegerUpDown controls instead, I get a similar error, but referencing the 'AutoMoveFocus' property (contained in UpDownBase<T>). This error doesn't prevent me from compiling and running my project just fine, but it does throw the error in the designer and prevent the design display from displaying my controls.

__Error__

Severity Code Description Project File Line Suppression State 'ParsingNumberStyle' property was already registered by 'Xceed_Wpf_Toolkit_CommonNumericUpDown`1_39_157692670'.
