How can we modify My Client Groups Person Search Views to display more detail

When searching on pages within My Client Groups (like Work Relationship), the search drop-down is only displaying Display Name and assignment number.

Prior to redwood, we would see Name, Work Email, Business Titles, Person Number etc.

When I go to Data Exchange > Search Views I do see the option for My Client Groups Person Search. Even though it's showing Work Email and Business Title, we don't see those displaying in the drop down. How do we add more fields to the search drop down to make sure users are selecting the correct search result?
