Only one slot to place anything in fridge

I noticed the game doesn't let you place things too close to the sides in houses (unless it's a window) so I was surprised it let me place the fridge this close to the corner on the back wall. I've been trying to put two monster meats in there, but it will only let me place anything on the bottom left spot and nowhere else. I haven't tried moving it over yet because then I'd probably have to move everything over.
