You can’t do what you’re attempting. The default value of a repeater sub field cannot be different for each row of a repeater.

What you need to do is load the entire value of all rows of the repeater.

Step 1: Set up your repeater so that it must have at least one row. This will ensure that it will have a value after someone has updated a post.

Step 2: use an acf/load_value filter, you will need the field keys of the repeater and the sub fields.

// the field key of repeater
add_filter(acf/load_value/key=field_XXXXXXX', 'my_acf_load_field', 20, 3);
function my_acf_load_field($value, $post_id, $field) {
  if ($value) {
    // if this field has a value then it has already be updated
    return $value;
  }
  // set up values of repeater
  if (have_rows('specifications', 'option')) {
    // initialize rows
    $rows = array();
    while (have_rows('specifications', 'option')) {
      the_row();
      // each row is a nested array using field key => value pairs
      $rows[] = array(
        // field key of the sub field
        'field_YYYYYYY' => get_sub_field('specification_name');
      );
    }
  }
  return $value;
}
