Data Table Row Editor - Can’t Edit Rows When Category specifier added

USTRUCT marco with Category specifier makes an ustruct member variable invisible in Row Editor Tab, Data Table asset window.

USTRUCT(BlueprintType, Category = "FileOp|JSON")
struct FSomeJSONStuff : public FTableRowBase
{
	GENERATED_BODY()
public:
/* visiable */
	UPROPERTY(BlueprintReadWrite, EditAnywhere, Category = "FileOp|JSON")
	FString FileName{"foo"};

/* Invisible */
	UPROPERTY(BlueprintReadWrite, EditAnywhere/*, Category = "FileOp|JSON"*/)
	FString FileDescription{"bar"};
}

Is this a bug or a feature? :thinking:
