Hi, ( sorry for the bad english i'll try my best to explain )

I'm actually moding the ProudspireManor but i have a problem now i really dont know how to fix this, i tried to move the bookshelf from the bedroom i moved everything ( the collision markers etc ) but when i go ingame i have an invisible bookshelf at the old place blocking the way , i can also us it, its just ... invisible and the one i moved is also usable

i saw someone asking help for the bookshelf and someone linked the turorial bookshelves so i decide to remove everything, delete the link to the "Xmarker" etc , after a save i try ingame , and the invisible bookshelf is still here !

how can i remove it plz ??
