DataAsset OOP is broken?

Development Programming & Scripting C++

I think I forgot mentionning but these are PrimaryDataAsset classes and then I create DataAssets from them:

UCLASS()
class UCustomClass : public UPrimaryDataAsset
{
	GENERATED_BODY()

public:
	UPROPERTY(EditAnywhere, Category = "Defaults")
	float Damage = 0.f;
};

And here’s the child PDA which is just containing few more variables:

UCLASS()
class UChildClass : public UCustomClass 
{
	GENERATED_BODY()

public:
	UPROPERTY(EditAnywhere)
	float RandomMultiplier = 0.f;
};

So I am able to create Data Assets from these 2 classes, and then select them in the array, but I can’t access (by casting) to the child at runtime in the array
