I'm having a small issue on a new board. Inside Pads, I have the layout set to remove unused inner layer pads to make it possible to route between vias on a bga. When I switch to the router, the pads are back in (it's not removing the unused pads). If I go back into Pads, the inner pads are gone. I've tried every setting I can think of, but the router just won't remove unsed pads. Can anyone offer some hints as to what I might be missing?
