Unable to change/edit elements of Blueprint instances of Actor Component set UObject arrays

When an array of custom UObjects is defined in an actor component class, blueprint instances of the component class cannot update the array elements. Array elements only update inside the blueprint, which changes all placed instances. This prevents separate instances from having separate arrays.

Regression:
No - behavior occurs in 4.13.2 and 4.14.0

1. Open UE4 Editor (any project)
2. Add code to project based on Object (MyObject)
3. Set UCLASS specifier with the following:

   (BlueprintType, EditInlineNew, DefaultToInstanced)

1. Add code to project based on ActorComponent (MyActorComponent)
2. Add TArray of UMyObject to MyActorComponent.h public

    UPROPERTY(EditAnywhere, Instanced, Category = "MyCategory") TArray<class UMyObject*> ArrayOfMyObjects;

1. Add code to project based on MyObject (SecondObject)
2. Compile code and make new blueprint based on Actor (ActorBP)
3. Add instance of My Actor Component to ActorBP
4. Select My Actor Coponent and add two elements to ArrayOfMyObjects
5. Set One element to MyObject and the other SecondObject
6. Place instance of MyActor into the level
7. Select My Actor Component in actor details
8. Click the field for element 0 (MyObject) and change to SecondObject

Result:
The element value will be unchanged and still show MyObject

Expected:
Element value can be set on instances of the blueprint
