Copy/Paste a data asset fields cause the fields to affect each other

When an element of a data asset is copied into another field, the two fields become "linked" and further edits to one field begin to affect the other.

1. Open UE4 Editor
2. Create an Object class (MyObject) and a DataAsset class (MyDataAsset)
3. In MyObject.h add the following Enum

   UENUM()
   enum class ETestEnum
   {
   	Random,
   	List,
   	Of,
   	Enumeration,
   	Values,
   	Count
   };
   

4. In MyDataAsset.h add the following:

   #include "MyObject.h"

   	UPROPERTY(Instanced, EditAnywhere, Category = "Default")
   		UMyObject* Data[ETestEnum::Count];
   

5. Compile
6. In the editor, create a new Data Asset (DataAssetBP)
   • Choose MyDataAsset as asset class
7. Open DataAssetBP
8. Set first dropdown to My Object
9. Right click MyObject and select copy
10. Right click another dropdown and select paste
11. Click the yellow arrow next to either dropdown box

Result:
Both dropdowns are reset to None

Expected:
Only the dropdown next to the clicked arrow updates
