Understanding Storm UI counts

Hi,
For my topology having a SQS spout to s3 bolt and then to a DB  Bolt, i
have ran a test for 10 K messages from SQS. I can see that the db bolt
which is last one in the tree shows 10K as the ack count. But all other
counts are different.
For eg: emit count from spout is double of incoming and s3 bolt also shows
double emit count. I have attached a screenshot. Can you please explain why
this discrepancy.
