I have updated a ship design a few times, and I am trying to delete the old inefficient designs, but I can't figure out how. I saved over them when I made the new ones, but they keep showing up in the "quick build" screen. I can't find them in the regular build screen where the delete option is. In addition, whenever I buy the ship, I get the old design that i don't want anyway. I can't buy the new one at all. I can't figure out why. Please help.
