Doctrine2 gives me only the first instance of related objects

Question

Doctrine2 gives me only the first instance of related objects

I use QueryBuilder to get the 10 largest cities with fortunes.

$query = $em->createQueryBuilder()
            ->select('c','s')
            ->from('CitiesBundle:Cities', 'c')
            ->innerJoin('c.state', 's','WITH', 'c.state = s')
            ->orderBy('c.population', 'DESC')
            ->setMaxResults(10)
            ->getQuery();

generated SQL:

SELECT c0_.id AS id0, c0_.name AS name1, c0_.landarea AS landarea2, c0_.density AS density3, c0_.population AS population4, s1_.id AS id5, s1_.name AS name6, c0_.state_id AS state_id7 from cities c0_ INNER JOIN s1_ ON c0_.state_id = s1_.id AND (c0_.state_id = s1_.id) ORDER BY c0_. population DESC LIMIT 10

When I test this request in PHPMyAdmin, each city has its own state, but in the application all the cities in the array have a connection with the state of the first city.

Can someone explain to me the behavior of Doctrine2 in this case?

Scheme:

XYZ\Bundle\CitiesBundle\Entity\Cities:
  type: entity
  table: cities
  fields:
  #fields
  oneToMany:
    state:
      targetEntity: States
      cascade: {  }
      mappedBy: null
      inversedBy: null
      joinColumns:
        state_id:
          referencedColumnName: id
      orphanRemoval: false
  lifecycleCallbacks: {  }


XYZ\Bundle\CitiesBundle\Entity\States:
  type: entity
  table: states
  fields:
    id:
      id: true
      type: boolean
      nullable: false
      generator:
        strategy: IDENTITY
    name:
      type: string
      length: 50
      fixed: false
      nullable: false
  lifecycleCallbacks: {  }
