There are multiple types of Gorgon Lens. One is the nice bright blue and one is the dull grey "lesser" Gorgon Lens. If you put both of these on a commodity vendor...it creates two lines...which is as expected and it does this for many items with the same name but different item id. The problem is when I went to price out the lesser...it just kept changing the price of the other line and not allowing me to set a price for the current item.
