Why does pagination in doctrine with orderBy c limit/offset/joins give the wrong number of results on DESC?

Question

symfony

Hello.
I have the following problem:
There is a class for working with queries, it creates queries for a selection with limit and offset, everything works fine, but if you execute a query for a selection by specifying orderBy = DESC
, the number of results does not match the expected one, for example, by specifying limit=20 and orderBy('column',DESC) will return about 7-8 results
Method - which collects the query:

the code

private function getQuery(string $entityStr): Query
    {
        $entity = $this->getEntity();

        /**
         * @var $manager EntityManager
         */
        $manager = $this->entityManager;

        $query = $manager
            ->createQueryBuilder()
            ->select('e')
            ->from($entityStr, 'e')
        ;

        $this->joinTables($query);

        $this->getWhereBy($query, $entity);

        $this->filterQuery($query, $entity);

        if ($entity->getGetLimit()) {
            $query->setMaxResults($entity->getGetLimit());
        }

        if ($entity->getGetOffset()) {
            $query->setFirstResult($entity->getGetOffset());
        }

        if ($sort = $entity->getGetSort()) {

            $order = $entity->getGetDesc() ? 'DESC' : 'ASC';

            $query->orderBy($this->getSortBy($entity), $order);
        }

        return $query->getQuery();
    }

The method that executes the request:

the code

public function findAllBy(string $entityStr): array
    {
        $query = $this->getQuery($entityStr);

        $paginator = new Paginator($query, true);
        $count = $paginator->count();

        $result = $paginator->getQuery()->getResult();

        return [
            'collection' => $result,
            'has_more'   => \count($result) + $paginator->getQuery()->getFirstResult() < $count,
        ];
    }

PS Locally ( Windows 7, php 7.1.6, doctrine/orm v2.5.12 ) everything works as it should, not on the server ( NGINX, php 7.1.12, doctrine/orm v2.5.12 )
