Hi Rusty, I followed your guide to set Catalog for Product. I check Default catalog for Product. But first time I check out with product, shipping address still null. But some next time, shipping address is show at receipt page. Is there any problem with cache in Merchello? When I check Catalog to Default for another product, the problem is similar.

I set Catelog to Default Category in live version, it still can't use shipping address? When I set Default Catalog for Product, I should reset IIS for web in live version?
