Querybuilder select() parsing problems

Cannot reproduce.

PHP Code:

<?php

namespace App\Controllers;

class Home extends BaseController
{
    public function index(): string
    {
        $db = \Config\Database::connect();
        $builder = $db->table('sales_items');
        $builder->select("name, sales.sale_id AS sale_id, sales.foo AS subtotal", false);
        return $sub_query = $builder->getCompiledSelect(false);
    }
} 


I see:

Code:

SELECT name, sales.sale_id AS sale_id, sales.foo AS subtotal FROM `sales_items`

or

Code:

SELECT name, sales.sale_id AS sale_id, sales.foo AS subtotal FROM `db_sales_items`
