Bill,
You really need to contact Henk69 the fellow that created the Chicken Calculator. Are you sure they do not have a wheaten with silver base (that is not a visual silver bird I am talking about it is a chicken of a different color) and some other dilutes. Remember recessive white will cover any color combintation so the birds you have could or could not be split recessive whites. They are definately a buff with extra genes to dilute the buff color. Good luck they look nice.
