Products caetegory position if there are subcategory is wrong

[Derres]

In normal category the position of products is the drag and drop of back office.

 

But if the category, have more subcategory, the products are mixed in a strange way. And the order is not the drag and drop order of the back office. Why ?

 

Where are the setting of that mix and with what criteria the prestashop mix the products in the category if there ar emore subcategory ?

 

Thanks
