Main category not honored when importing products

[Cwardia]

Hi,

I am quite new in Prestashop and maybe I am doing something wrong...I am trying to import my products and main category is not honored by the import: One of my categories is:

Init-Clothes, .csv file column is defined Init,Clothes.

Products are imported OK, but when I check the back office product page I see main category check (should be Clothes in my case) hasn't been honored by the import but Init was chosen instead.

Any ideas?

Thanks a lot in advance,
