.csv import says "already existing products"

-- HikaShop version -- : 2.6.4
-- Joomla version -- : 3.6.2

I am trying to create products via .csv upload, however I keep getting the error message:

"60 products found : 0 new products imported, 0 invalid product code, 60 already existing products"

I have read the threads on the forum which advise removing the product_id column data, but this makes no difference.

None of these products are already existing.

.csv file attached, is there anything that I need to add/subtract to make it work?

Thanks for your reply.

Yes, that's what the problem was. After checking, the products actually successfully uploaded.
