Unable to Start Flow Capture with HP Switch

Hello,

I've seen various posts here with similar problems but no definitive answer... can anyone help?

I've configured an HP switch to send sFlow data to my PC for analysis with the Real-Time NetFlow Analyzer.  I cannot start the flow capture because the interface for which sFlow is enabled is not showing as "sending NetFlow" and there is no green icon.

I have confirmed that the switch is sending the data and that the PC is receiving by using a packet capture.

I was hoping to use this free tool as an indicator of what data I might expect to see if I purchased Orion NFA but I'm failing at the first hurdle unfortunately.

Any suggestions would be greatly appreciated!

Switch output:
