ASA 5540 Netflow packets don't contain byte data

Hello.

We use ASA 5540 with 8.2(1) (we can't update it).

I have configured netflow with commands:

flow-export destination inside 192.168.1.93 9997
flow-export template timeout-rate 1

policy-map global_policy
 class flow_export_class
  flow-export event-type all destination 192.168.1.93

service-policy global_policy global

 

Now I'm tying to collect netflow into Splunk. And there is no field "bytes" in netflow packages. I capture some packages with Wireshark.

For examle there is field "Bytes" in templates (id=0) for events with id=256. But there is no field "Byte" in Netflow packages proper

I saw this topic but there is no field "Byte" at all. And I use very old version IOS.

How can I add fields byte and packages?
