Error in my robot path

When I run my path I get these “errors”

  1. “Validation error: Target element must be set”
    However, this is a ‘Type into’ action whereby I typed in my email address to test if the robot will send me a mail

  2. “Validation error: The card can not be inside an application card”
    This is my biggest concern as I didn’t get when to close a card and start a new one. Can someone please assist me with this.
