why the exact profile can't work in windows performance recorder on surface RT(ARM)?

Hi,

I just try to use profile with a ETW sample from MSDN 

Logging Sample for Windows Store Apps (ETW Logging in WinRT)

They works fine on PC/x86 which mean when I open the dumped *.etl file the name of provider/event will be displayed as "MetroEventSource/Info"

But on SurfaceRT when I open the dumped etl file I can't find the correct provider/event name.

Could you help? thanks

Here is the profile
