I figured it out. I was trying to draw the front-end field name. I needed to go into SQL and get the correct row used there.
add_filter('acf/load_value/name=employee_schedule', 'my_acf_load_value', 10, 3); //repeater_name
function my_acf_load_value( $rows)
{
foreach( $rows as $key => $row ) {
$column_id[ $key ] = $row['field_5625599634aa1'];
}
array_multisort( $column_id, SORT_ASC, $rows );
return $rows;
}
