Encryption Server daily email report is inaccurate

Encryption Server v 3.3.2 MP7 & Encryption Desktop 10.3.2 MP7

Our Daily email report shows data we know to be inaccurate; (ie.) Amount processed is about half of actual processed mail, Encrypted today should never be (0) zero, Total encrypted is at 13 for over 30 days, Total decrypted should also not be at (0) Zero.

How can I go about getting the logs to report the proper data?
