Hideout Decor 1 Use only

I bought a Hideout decoration (Nightfall building supplies) and I can only place 1 instance of this decoration, instead of copying it and multiplying throughout the hideout.
Using other items, such as Cave Pillar, I can place a large amount of same model items.

Edit: Same thing is happening with Madcap Tree, a hideout decoration i bought and can only place 1 instance.
