You CAN go to that link, & click on "UPDATE", use the pull-down menu under "No change" to select "Correct/Delete", then click "Continue". Then scroll down to the one you want to correct, & select the Pull-Down menu to change it from "Keep" to "Correct". Then scroll down to "Continue". Now, you can make the correction, & even tell them WHY you are correcting it. When you"Submit"it, they will review it, then if they decide the correction IS needed, they will accept it & update the record.
