Combat engraving books are bugged

Basicly that type of book is bugged, and is missing quite some engravings. If I compare it to another stack i have , those DO have all the engravings. I’ll show both examples. The 40 stacks I have are the bugged one, look how the last option is Awakening book, while the 4 stack, goes beyond that. Cause a guildmate was going nuts trying to find adrenaline in the books from event, and for some reason it just isnt in that book (its the stack of 40 ). They have the exact same name and everything, its soo weird.


Other bags has 33 engravings you can choose from while Super exchange engraving bags only has 24 engravings.
