Child actor cannot set to hidden when run in standalone mode

I create a child actor component and spawn an actor.
Everything seems perfect when I run in Editor mode. However, when I run in Standalone mode, the child actor is not hidden.

Below is part of my code:

.h

	UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = "Drone")
	UChildActorComponent* DirectionChildActorComponent;

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Drone")
	ADirectionActor* DirectionActor;

.cpp

ADroneBase::ADroneBase()
{
 	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

	// Some other unrelated code here

	DirectionChildActorComponent = CreateDefaultSubobject<UChildActorComponent>(TEXT("DirectionActor"));
	DirectionChildActorComponent->SetupAttachment(RootComponent);
	DirectionChildActorComponent->SetRelativeLocation(FVector(0.0f, 0.0f, 0.0f));
	DirectionChildActorComponent->SetChildActorClass(ADirectionActor::StaticClass());
	DirectionChildActorComponent->CreateChildActor();
}

void ADroneBase::BeginPlay()
{
	
	Super::BeginPlay();

	UDroneFunctionLibrary::ExecuteMiniSv();

	DirectionChildActorComponent->CreateChildActor();
	DirectionActor = (ADirectionActor*) DirectionChildActorComponent->GetChildActor();
	DirectionActor->SceneComponent->SetVisibility(false);
	DirectionActor->SetActorHiddenInGame(true);

	//Just for test, and result in "DirectionActor: DirectionActor_DirectionActor_CAT_0"
	GEngine->AddOnScreenDebugMessage(-1, 15.0f, FColor::Red, FString::Printf(TEXT("ADroneBase::BeginPlay(), DirectionActor: %s"), *DirectionActor->GetName()));

}

What am I doing wrong in my code?
Or is it a bug for UE4?

Thank you
