Without stock?

I have a small problem here. When I import items, regardless of whether or with ASIN browseNode, the sizes are not imported. That is, for example, in clothes or shoes that. Items are not available as (without stock) angezeigt.Gibt Is there a setting somewhere?
If it is not otherwise, it is practically impossible to import products with size specification to import ;-(.


Sorry for the bad english (Google 😉
