php - Display ACF product custom fields everywhere in WooCommerce 3+

I am building a site using WooCommerce and Advanced Custom Fields (ACF) plugin. I've created two ACF custom fields with names "plant" and "amount".

I am trying to display them both on front end but currently only the custom field "plant" is displaying everywhere. I've been looking around the net with no luck.

add_action( 'woocommerce_before_add_to_cart_button', 'add_custom_field', 0 );

function add_custom_field() {
    global $product;             // Changed this

    // Added this too (compatibility with WC +3) 
    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    echo "<div class='produto-informacoes-complementares'>";
    echo get_field( 'plant', $product_id );
    echo "</div>";
    echo "<div class='produto-informacoes-complementares'>";
    echo get_field( 'amount', $product_id );
    echo "</div>";


    return true;
}


add_filter( 'woocommerce_add_cart_item_data', 'save_my_custom_product_field', 10, 2 );

function save_my_custom_product_field( $cart_item_data, $product_id ) {

    $custom_field_value = get_field( 'plant', $product_id, true );
     $custom_field_value = get_field( 'amount', $product_id, true );

    if( !empty( $custom_field_value ) ) 
    {
        $cart_item_data['plant'] = $custom_field_value;
         $cart_item_data['amount'] = $custom_field_value;

        // below statement make sure every add to cart action as unique line item
        $cart_item_data['unique_key'] = md5( microtime().rand() );
    }
    return $cart_item_data;
}

add_filter( 'woocommerce_get_item_data', 'render_meta_on_cart_and_checkout', 10, 2 );

function render_meta_on_cart_and_checkout( $cart_data, $cart_item ) {
    $custom_items = array();
    // Woo 2.4.2 updates
    if( !empty( $cart_data ) ) {
        $custom_items = $cart_data;
    }
    if( isset( $cart_item['plant'] )) {
        $custom_items[] = array( "name" => "?�?�?�?? ???�?�??", "value" => $cart_item['plant'] );
        $custom_items[] = array( "name" => "?�???�?? ?�???�?�", "value" => $cart_item['amount'] );
        
    }
    return $custom_items;
}

function add_order_item_meta_acf( $item_id, $values ) {

    wc_add_order_item_meta( $item_id, '?�?�?�?? ???�?�??', $values [ 'plant' ] );
    wc_add_order_item_meta( $item_id, '?�?�?�?? ???�?�??', $values [ 'amount' ] );
  }
add_action( 'woocommerce_add_order_item_meta', 'add_order_item_meta_acf' , 10, 2);
