In order to pre-populate a repeater and have unique values for each row you need to populate the entire repeater in one go.

here’s an example:

add_filter('acf/load_value/key=field_123456', 'pre_pop_repeater', 20, 3);
/* in the above the field_123456 is the field key of your repeater */

function pre_pop_repeater($value, $post_id, $field) {
  if ($value != NULL) {
    // if the acf value is not null then
    // repeater was previously saved
    // and we should not override
    return $value;
  }
  // return an array
  $value = array(
    // each element of the array represents a row
    array(
      // this is the first row
      // set value for every field in the row
      // the values are field_key => value pairs
      'field_678' => 'value for this field',
      'field_789' => 'value for this field'
      // etc...
    ),
    array(
      // this is the second row
      // etc....
    ),
  );
  return $value;
}
