How can I initialize properties from DataTable specified in Blueprint Class?

I have URPGAttributeBase class, which have property:

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Data")
UDataTable* AttributeDataTable;

And I set this property in Blueprint Default Properties in Editor.

I have also URPGAttributeComponent class:

Which takes:

UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Attributes")
TSubclassOf<class URPGAttributeBase> AttributeClass;

UPROPERTY(BlueprintReadOnly, Category = "Attributes")
URPGAttributeBase* Attribute;

And then:

void URPGAttributeComponent::GetOrCreateAttribute()
{
	if (AttributeClass)
	{
		if (!Attribute)
		{
			Attribute = ConstructObject<URPGAttributeBase>(AttributeClass);
		}
	}
}

And Attribute is created properly. Expect that:

AttributeDataTable

Is Null. Any idea why it is not passed from blueprint, while contructing object ?

Where do you exactly use AttributeDataTable? There possibility that Blueprint defaults are yet to be applied a tstage you referring to AttributeDataTable
