Interface utilization capture is not correct

Interface utilization capture is not correct

Facing problem in Interface utilization capture in Netflow Analyzer version 9.8.5

Configured all the possible commands in the interface and global level:

ip flow-cache timeout active 1
 ip flow ingress
 ip flow egress
ip flow-export source GigabitEthernet0/2
ip flow-export version 5
ip flow-export destination 172.16.177.57 9996
ip access-list standard Netflow
snmp-server community tcs#boa RO Netflow

But still the utilization in NFAnalyzer and Router interface are having too much difference(more than 100%). Any solution to this issue?
