Loading Key member using API keeps using the person_previous_last_name

I am using the pa_project_pub.load_key_member to load key members to a newly created project. Out of the 3 members loaded, 2 of them get created correctly but the last one get created with their previous name.

I have queried the data from per_all_people_f and the correct row is being selected when I using toad.

The api call is ...

pa_project_pub.load_key_member( p_api_version_number => l_api_version_number,
                                              p_return_status => l_return_status,
                                              p_person_id => l_key_member_tbl( l_role_count).person_id,
                                              p_project_role_type => l_key_member_tbl( l_role_count).project_role_type,
