I've been working on customizing my Proudspire Manor house for over a month. I am just about finished, but the room next to the bedroom I am trying to turn into a library. This means adding some bookshelves, which I have had zero success with. I've tried literally moving a bookcase and its markers from other locations in the house. What happens is when I put a book in the shelf, it disappears and pops out where the bookshelf used to be. I've tried copying and pasting bookshelves, etc with no results.

I'm not an advanced user of the creation kit. All I know how to do is move furniture around and other basic stuff, I don't know scripting. I've read tutorials on how to make bookshelves, but it is too complex and time consuming just for one single bookshelf. Can someone please tell me if there is a shortcut so I can fill my library with books?
