Approver Receives Duplicate Emails (one for each line) when Exp Rpt and TA Route to their Worklist

In 9.2 Image 11, Peopletools 8.54 an approver receives a duplicate email - one for each line - when an expense report and/or travel authorization enters their worklist. I've reviewed the configuration on the Transaction Configuration page, but cannot find what need to be changed for the approver to only receive one email for each claim that enters their worklist and not for each line. I tried changing the event to a status of "Header" instead of "Line", but the outcome is the approver then receives no emails when a claim enters their worklist.

See attachment for current set up for events on the Transaction Configuration page pertaining to claims entering a worklist.
