Name in Employee Profile and Employee Directory not in sync

Hi Expert,

Need advise.

Employee last name appears different in Employee Profile and Employee Directory ( name in search tab).

Issue: Employee last name ( eg JOHNSON) entered during hiring was incorrect , hence later admin corrected the employee last name to ( JOHNSONS) .

In Employee profile the last name is reflecting correctly as JOHNSONS however in search tab the employee is still appearing as JOHNSON .

Please explain how this needs to be synced.

Appreciate your help.
