Defensive Winger role rating

How is this role rating made?

The rating is different for defensive and supporting duties and in the game the highlighted attributes are the same in both duties. I think it's weird because since this happens too in the winger role but in that case the rating is the same for the two available duties.

All highlighted attributes are just they key attributes for a role. There are other attributes which affect the role rating.

Then why do winger attack and support duties have the same role rating?
