Sqlite adapter find/update are not working when working with models

I have the basic of basic of codes

My bootstrap file

<?php

//...

use Phalcon\Db\Adapter\Pdo\Sqlite as DbAdapter;

//...

    // Setup the database service
    $di->set('db', function () {
        return new DbAdapter([
            "dbname" => "/Users/saginadir/sqlite/vmessages.sqlite"
        ]);
    });

My Users Model file

<?php

use Phalcon\Mvc\Model;

class Users extends Model
{
    public $id;

    public $name;

    public $email;

    public function initialize()
    {
        $this->setConnectionService('db');
    }
}

My DB table:

CREATE TABLE users
(
    id INTEGER PRIMARY KEY,
    name TEXT,
    email TEXT
);

My Controller file

<?php

use Phalcon\Mvc\Controller;

class UsersController extends Controller
{

    public function getUser()
    {
        $userFromQuery = $this->di->get('db')->fetchOne("SELECT * FROM users WHERE name = 'John'");
        $users = new Users();
        $user = $users->findFirst(["name" => "John"]);
        var_dump($user);  // id = 1 DIFFERENT ID FROM BELOW!
        var_dump($userFromQuery); //id = 2 DIFFERENT ID FROM ABOVE!
    }
}

In the case above, when i fetch a row using my db connection I get id = 2, which is correct, but when I try to fetch rows using my model, I get id = 1, all the time.

Anyone has this issue? am I doing something wrong?
