Set dunegon need help

Hello there i cant do any of the “Set Dungeons”
Someone can help me ? im Front of the Dungeon set book it and when i click on the book
" YOU ARE NOT APPROPRIATELY TO READ THIS TOME"
So what i can do ?
Its on t16 i try on season adn non-season.
Same think!

There are no set dungeons for the newest set armours, i.e.

Class No Set Dungeon Has Set Dungeon
Barbarian Horde of the Ninety Savages Immortal King, Might, Raekor, Wastes
Crusader Aegis of Valor Akkhan, Invoker, Roland, Seeker
Demon Hunter Gears of Dreadlands Marauder, Natalya, Shadow, Unhallowed Essence
Monk Patterns of Justice Inna, Raiment, Sunwuko, Uliana
Witch Doctor Mundunugu’s Regalia Arachyr, Jade, Helltooth, Zunimassa
Wizard Typhon’s Veil Delsere’s, Firebird, Tal Rasha, Vyr
Necromancer Masquerade of the Burning Carnival Inarius, Pestilence, Rathma, Trag’oul

What this means is that, in a season where the Haedrig’s Gifts grant these sets, in order to complete the Season Journey tasks for completing and mastering a Set Dungeon, you will need to farm one of the other class sets and complete the dungeon associated with that set.

It is not a bug that the new sets do not have dungeons associated with them. When the first of these new sets were released it was queried whether new set dungeons would be created for them. Blizzard confirmed that not only were there no new dungeons, but that they had no intention of creating any.
