Campaigns From Email

Campaigns From Email

We have been experiencing an odd issue.  One of our users creates campaigns and sends them out but they are appearing to our clients to be coming from other employees within our company.  It seems random, 2 or 3 will be from me and 5 or 6 from another employee.  The users is setting the from email as his but it seems to come from others.  

In the send details I see that "CRM Data Enabled" is displayed for alternate Sender Email and Reply Email.  Does this have something to do with it?
