In the player's house Interiors->WhiterunBrezeehouse (FormID 000165A8) I duplicated a book shelve (CommonShelf03 FormID 000ce784 near the fire pit) AND the book proxys, container, triggers, collision boxes etc..

When I enter the house the duplicated book shelve is there and it shows the "E to interact" text, but when I press E nothing happens (I'm supposed to get up the book shelf manager).

I have compared all the settings and links for all objects and they are the same. Same script names, same references...

Any clue of what it might bee?

...or is there another way to add in a new managed book shelf?
