Asus RT-AC3200: Traffic Analyzer broken in _4149?

Looking for some help/confirmation

Just out of box 3200

Traffic Analyzer screen indicates (w/ Sample data, cuz off by default) that per app stats can be analyzed, i.e. YouTube, Dropbox, etc...

Once it's turned on and I select=> Display for: Router [Apps]
All I see is all traffic clumped in "General"

Anyone else seeing this? on latest FM: _4149?
Have I enabled some other feature which breaks/disables this?

Thanks
Enzo
