Missing hostname in the server response

Product: Flowmon Collector
Why is the hostname missing in the server response?

This behavior can be observed when "Add enabled L2 fields to the NetFlow identifiers" is enabled in the Configuration Center - Monitoring Ports - Advanced settings.
This feature causes MAC addresses to be considered as a key field for creating flow records (standard key fields are IPs, ports, and L4 protocol), and in some cases (e.g. proxy is used in the HTTP/S communication), it can break flow pairs (request/response).
