Populate command does not loop through every elements

When I launch a populate command (with reset), the progress bar does not complete to 100% on some types. There is no error, bulk is processed as expected by elasticsearch. (I added an echo output for debug process)

php app/console fos:elastica:populate --no-debug

https://github.com/FriendsOfSymfony/FOSElasticaBundle/blob/3.2.1/Doctrine/AbstractProvider.php#L89

it's seems that the $offset is incremented by $options['batch_size'] instead of $sliceSize. Using $sliceSize seems to fix the problem.

The query used to index elements is here:

        $qb = $this->createQueryBuilder("e")
            ->select("e,d")
            ->join("e.dates", "d")
            ->join("d.placeArea", "pa")
            ->join("e.organisation", "o")
            ->where("d.endDate > :ago or d.endDate is null")
            ->setParameter("ago", new \DateTime("2 months ago"))
            ->andWhere("e.status in (:status)")
            ->andWhere("o.status in (:status)")
            ->setParameter("status", [StatusInterface::STATUS_APPROVED, StatusInterface::STATUS_MODIFIED]);

I am using with php5.6+, vendors are below:
