I want to hide some function on blueprint but HideFunctions not works properly.

But HideCategories works fine.

is it bug?

UCLASS(HideCategories=(HiddenFunction), HideFunctions="HiddenFunc")
class TESTPROJECT_API ATest : public AActor
{
	GENERATED_BODY()

public:
	UFUNCTION(BlueprintCallable, Category = HiddenFunction)
	void HiddenCategoryFunc();

	UFUNCTION(BlueprintCallable)
	void HiddenFunc();
};

It seems to conflict with BlueprintCallable. There’s no reason for it to be hidden if it should be callable, and the engine recognizes this, giving priority to BlueprintCallable.

Since HiddenFunction is a category that just doesn’t appear, it doesn’t seems to conflict.

Honestly the more I think about it, the less I get why HideFunctions even exists. Unlike the category, it even hides it from the override functions list.
