Commerce Server's Biz Desk and Category Sorting

I’m using Attain 3.6’s Commerce Portal that utilizes Microsoft Commerce Server 2000’s Business Desk to deliver Item Card information stored in SQL onto my web site. The Category in the Business Desk is always sorted ascendingly. I see the “Move Up” and “Move Down” buttons which suggest that I can manually manipulate the order of the categories to be shown on the web. However, after making the changes, and upon saving it. The change always lost and the sorting comes back to ascending. Does anybody know how to save the change?
