Populate repeater from options page repeater custom fields

I have an options page using ACF

This is the structure (OPTIONS PAGE)

- specifications - group

-- specifications_repeater - repeater

--- specification_name - text

so on the options page I added 3 fields and save

Size
Range
Colour

Now I have another another custom fields set in pages

- specifications - repeater

-- specification_item - text (populate this fields based on the "specification_name" field on the options page)

-- specification_value - text

What I want and hoping that it populates whatever its in the options page, so it will populate automatically the fields ( Size, Colour & Range )

I have this code below but it only populates “Colour” on all its fields, I think its pulling the last data.

function my_acf_load_field($field) {
    $field['default_value'] = array();
    if( have_rows('specifications', 'option') ) {
        while( have_rows('specifications', 'option') ) {
            the_row();

            if( have_rows('specifications_repeater', 'option') ) {
                while( have_rows('specifications_repeater', 'option') ) {
                    the_row();

                    $value = get_sub_field('specification_name');
                    $field['default_value'] = $value;

                }
            }

        }
    }
    //$field['default_value'] = uniqid();
    return $field;
}
add_filter('acf/load_field/key=field_5e86e1166f98a', 'my_acf_load_field');

also

field_5e86e1166f98a

is the target field

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;
}
