Add net clicks on campaign statistics group by email

I was investigating, in fact it is a bug:

$clickedCount = $this->getEntityManager()->getRepository('CampaignLogRecord')->where(array(
            'campaignId' => $entity->id,
            'action' => 'Clicked',
            'isTest' => false,
            'groupBy' => ['queueItemId']
        ))->count();
        $entity->set('clickedCount', $clickedCount); 

This query return the "Image 1" picture.

The query should be like "Image 2" picture.
