I know pretty well Magento and the M2E PRO extension but I have a small problem.
When I add a description policy, I select yes for ASIN creation if prodoct don't exist and the 2 mandatory fields : Brand and Manufacturer (may depend on your translation).
In my case, I can't find even one of these 2 attributes in the assigned dropdown. Why ? Do they need a special setting ? I assume that some items may have an empty brand. Is it enough to make the attribute disappear from this dropdown ?
These attributes exist and are shown underneath in another dropdown the ones for Search term value and Bullet Points Value.
Thanks for your help !
