Purchased a scenery and it can only be used in war base?

Started playing the game a couple weeks ago with my bf and we don't even really know what a war base is. He bought a scenery he liked but it's only an option in the "war base" tab and not "home village". We rechecked and nowhere did it say it wouldn't be usable in your home village pre-purchase. What are we supposed to do? He no longer wants it since it can't be used
