Classic reconstructing fear and flesh

So do I only need 2 pages and the quest is bugged and shows that I need 4 or did the information about the cloak catch up get confused? I've heard you only need 2 pages per rank and that the quest is bugged and still shows you need more, but I've got 3 now and can't turn it in, or is that the issue, that I actually have to many? via /r/wow https://ift.tt/3gGP4E4
