Netflow doesnt seem to identify Interface in Router

Netflow doesnt seem to identify Interface in Router

I'm using Netflow Analyser 5 to view traffic on a cisco router with 2 Serial interfaces and 1 ethernet interface. Currently it tracks one serial and 1 ethernet interface.

I dont know why its not tracking the second serial interface,

What i tried is, went to the license management, made the Ethernet to unmanaged, so as to make one license free

But i still dont see the second serial interface, not sure where the problem is since it detects 2 interface but not the third one.

let me know what i should to capture the second serial as well
