This is a Bug Alert for the new sales categories used in conjunction with a Pricing Method. If you setup a new Sales Category in one of the new slots added under preferences (Slots 22-40) and then assign that category to a pricing method the sales will get assigned to category #1 by default. Obviously, this is a fairly major bug.
In the meantime, you can create a charge that is assigned to the new categories (22-40) and the charge will assign the category correctly. I will post more detail when I find out more.
