VTune display nothing when I run 'vtl view a1::r1'

Hi, I got some very strange errors with Intel Vtune utilities. I have run:

vtl activity -c callgraph -c sampling -app ./vtunedemo -moi ./vtunedemo run

to collect data. And,

$ vtl show

but

$ vtl view a1::r1

I got nothing output. I have try to add some other options:

$ vtl view a1::r1 -mn ./vtunedemo

$ vtl view a1::r1 -mn ./vtunedemo -calls
