Update products with CSV - How to edit the package weight

[edenlov]

Hello,

I'm trying to edit the weight of the packages with the CSV file transfer, but I can't.
According to the help PDF files, I should use "WeightMajor" and "WeightMinor" but that doesn't work. This deletes the current weight of the package but does not replace it with the new data.

I work on Ebay French version.

Thanks to help me.
