hideCategories = (ActorTick) won't work in 4.12

i have checked it again with some classes and all this different classes still showing ActorTick category.

First i thought that it happens only with classes which has default customization pannel, but not, i think issue happens for categories with consists of 2 words started in upper case like “Actor Tick” and as upper example with “WeaponSets”

Here is example with class:

#pragma once
#include "T_PickupItem.generated.h"

UCLASS(Abstract, hideCategories = (ActorTick, Rendering, Replication, Input, Actor))
class AT_PickupItem : public AActor
{
	GENERATED_BODY()

};

result:

Only ActorTick hidden:

#pragma once
#include "T_PickupItem.generated.h"

UCLASS(Abstract, hideCategories = (ActorTick))
class AT_PickupItem : public AActor
{
	GENERATED_BODY()

};

result:

As you can see all categories except ActorTick was hiden fine.

Same thing happens with many different classes extended from AActor. And this started since 4.12, in 4.11 this category was hidden fine.
