Antoaneta,
The status column tells you the issue: "User not added - error" and the cause is shown in the Email address column: "Duplicate address."
Most likely you may have chosen as Upload type the "Add new only, skip existing users" and it generated the error since this second user is not is not a new user like the one in the first line. Try choosing "Add new and update existing users" as the Upload option to see if that works.
