Build Buy wont let me place objects

I tested a new save file and it seems to be on only this one save file. I tested without mods and the problem persists. When I go into build/buy, I can place the first object (multiple if it's something like a counter) but once I deselect that object and try the next, it constantly deselects the object before I can place it. It's a battle of spam clicking just to place one object. I just started the save file and was changing the apartment I put them in to accommodate the fact they have an infant.
