Why need "name_xx" column for update quantities? I think need only sku.
Unfortunately, that is how the import tool is designed to work, it identifies a product by name&sku.
A new 'Update inventory' module is scheduled to be released with X-Cart 5.2.11 in the beginning of 2016. It works pretty much like the 'update inventory' feature in X-Cart 4, and will only require sku & stock level to update product quantities.
