I'm checking to verify this, but from the Help system:
"Except for the Configuration and Recovery states, the substates are not displayed for any other state. For instance, the substates of Polling such as Polling.Active, Polling.Compliance and Polling.Configuration are not displayed. Only the Polling state is listed in the pane."
I suspect that the reason is that the current state and substate are inferred from the captured data, it may not be possible to determine other substates reliably.
Disclaimer: For more reliable response, you should consider calling your local Keysight Technical Call Center. The Keysight Forums are monitored on an "as available" basis, and aren't necessarily the fastest way to get technical questions answered.
