Traffic total not accurate

Traffic total not accurate

I have one Cisco ASA device connected to my instance of netflow analyzer. The total traffic reported seems to be about 2x what the actual traffic is. As an example, I host an FTP site and by analyzing the FTP logs can determine the amount of data sent to the FTP server. The issue is for the same IP address in netflow analyzer - I get 2x the bytes. I am monitoring both the Untrusted and Trusted interface on the ASA. What could cause this? We just moved to netflow as our firewall was just replaced.

Thanks,
