Please help...

I am using Zen Cart 1.3.8a

my site is under development at: http://centaurhorseshop.co.za/shop/

Occasionally, if you navigate to saddles ( a category) and then click on a subcategory, the breadcrumb at the top indicates that the subcategory is a subcategory of Veterinary, another category.

I have tried moving the products around, and it seems to be related to the one category, Saddles. The products are not linked to other categories.

It does not seem to happen with other another test product that I have put under Clothing > Gloves

Any ideas would be helpful!
