Cannot add Instanced UObjects to ActorComponents who belong to Actors placed in the level.

When a Actor Blueprint is placed in the world with a TArray of instanced UObjects, the + button to add a new instance of the object wont create a instance of the object.

1. Create new C++ empty project
2. Create UObject inherited class with following code:

   #pragma once
   
   #include "Object.h"
   #include "DeadObject.generated.h"
   
   /**
   *
   */
   UCLASS(BlueprintType, EditInlineNew)
   class AH454593_API UDeadObject : public UObject
   {
   	GENERATED_BODY()
   
   public:
   	UDeadObject();
   
   	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "DeadObject")
   	int TestValOne;
   
   	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "DeadObject")
   	float TestValTwo;
   
   };
   

3. Create ActorComponent inherited class with the following code:

   #pragma once
   
   #include "Components/ActorComponent.h"
   #include "DeadComponent.generated.h"
   
   UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
   class AH454593_API UDeadComponent : public UActorComponent
   {
   	GENERATED_BODY()
   
   public:	
   	// Sets default values for this component's properties
   	UDeadComponent();
   
   	// Called when the game starts
   	virtual void BeginPlay() override;
   	
   	// Called every frame
   	virtual void TickComponent( float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction ) override;
   	
   	UPROPERTY( EditAnywhere, BlueprintReadWrite, Instanced, Category = "UDead Objects" )
   	TArray<class UDeadObject*> DeadObjects;	
   };
   

4. Compile project.
5. Create Blueprint class in editor, from Actor.
6. Add "Dead" Component to Actor Blueprint.
7. Place Blueprint into level and select the "Dead" component from the Component details panel.
8. Under "UDead Objects", press + button to add to "Dead Objects"

RESULT:

Pressing the + button for an instanced object TArray wont add any elements.

EXPECTED:

Pressing the + button adds to the TArray of instanced objects.
