Crafting IX Books cannot be sold or discarded

My character in game bought books in advance of level 90 and I had one in my Saddlebag. As such, I was tired one night doing Studium crafting and getting White Crafter's Scrips.

I had bought Master Carpenter IX and cannot use it until level 90 woops.
Okay, I can eventually use it so I put it in my saddle bag to store.

I continue to craft and gather scrips and then go to buy another book. I thought I pressed Blacksmith but I had accidently pressed carpenter again so now I have two copies of Master Carpenter IX. I can only use one at level 90 and unfortunately, it cannot be sold or discarded....am I going to have this permanently take one of my inventory spaces forever?
Please advise!

Thank you!!

once you finally use the book you can discard the 2nd copy. until then you'll have to keep lugging it around.

Oh, I see!! Thank you so much!! I'm glad to hear that. I feel better already!! Sad I can't trade it in for a different book though...oh well...better than what I thought! Thanks again!
