Hola Ubercarts...

I'm having some issues moving products between categories. I'm trying both of the ways that have worked in the past;

a) Edit product and change category
b) Use "move product" (under ubercart admin)

The problem is that a duplicate category is generated and the product is moved to that.

I'm using UC to sell menu products at www.menucovers.com.au, I wanted to move one item from "Fine Dining" to "Pub & Cafe" but instead of moving to the existing category, I get a new "Pub & Cafe" in addition to the existing.

Any ideas?
