Difficulty with Spirit Sentinel Turn in (Shaman Epic)

[Kosmic Utensil]

I'm having difficulty combining the 6 reports from City of Mist into the journal the Spirit Sentinel gives in Emerald Jungle. I have put all 6 pages into the book but keep getting an error message saying 'these items cannot be combined in this container type.' I confirmed they are all the correct pages (and they are Lore so no duplicates possible) and that they are absolutely in the right container instead of a random bag. I petitioned in game but got a response that they do not help with issues like this.

Anyone have this issue before? Appreciate the input.

Thanks,
