Missing field

I am using filebeats panos module. In the index i don't see the source.geo.name or destination.geo.name if i select the event.category as network_traffic. Although it shows as country ISO_code but not by name. Actual syslog is below which shows the countries name. How can i get name also in the index.

source/destination geo.name field is there in even.category : security_threat

below is the event.category : network_traffic raw log
