Perhaps there is confusion about the direction the switches should be to set address 7? If all four were inverted you would get address 8, which is what you are seeing? I've seen this with other pieces of equipment, or even worse, the switch part used was changed at some point and the new switch type needed to be set the "inverse" way to behave like the previous switch type.
