All interfaces are detected in Netflow but NO Traffic In/Out for CiscoASA 5500-X

All interfaces are detected in Netflow but NO Traffic In/Out for CiscoASA 5500-X

I know I have configured my new CiscoASA 5516-X and 5525-X FWs right according to my existing CiscoASA5520. I just copied the same procedure in ASA from SNMP and  Service Policy Rule based from my ASA5520. The OPManger Netflow has already detected the ASA devices and interface and even showing status is up and updated flow. However, I still havent gotten any IN and OUT traffic. I need help where I missed.
See attached the issue of IN and OUT
