GetAttachParent return null in PostEditChangeProperty

Hello! I am writing component which rotate it parent component (attachment):

void USpinnerComponent::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
	Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

#if WITH_EDITOR
	if (!PreviewInEditor) {
		return;
	}
#endif
	USceneComponent* parent = GetAttachParent();
	if (parent) {
		/// do something here
		 parent->AddLocalRotation(rotation);
	}
}

And this work fine.
But when some property changed I need to save parent state but I can not reach my parent any more:

#if WITH_EDITOR
void USpinnerComponent::PostEditChangeProperty(FPropertyChangedEvent & e)
{
	Super::PostEditChangeProperty(e);
	if ( e.GetPropertyName() == GET_MEMBER_NAME_CHECKED(USpinnerComponent, PreviewInEditor)) {
		USceneComponent* parent = GetAttachParent();
		if (!parent)
			return;
		if (PreviewInEditor) {
			BeforePreview = parent->RelativeRotation;
		}else{
			parent->ResetRelativeTransform();
		}
	}
}
#endif

Parent is ALWAYS null, even more in debugger I can see that my object name is “TRASH_SpinnerComponent” or “Spinner_GEN_VARIABLE” while in TickComponent name is always “Spinner”. And I have only one instance of this component in scene. What the hell is happening?
