Delete Resolved Models From Component Family

Hello,

How can I bulk delete parts created in the system from the platform with the help of Component Family? There is a command called Delete Resolved Models in the Component Family Definition application, but the parts are not deleted. I get a response like ScreenShot_1.

Can you explain the working method of the Delete Resolved Models command? Or should I delete these parts with another method?

ScreenShot_1
