eye data : v2 not returning coherent values for squeeze, frown and convdist

[SIMU EAN]

Hi, 

I managed to extract the eye data with v2 at 120Hz from Unity. All values seem to be coherent except eye squeeze, conv distance and frown.  Eye squeeze often returns zeros and sometimes other values but i don't see how to interprete them. 

Frown and convdist return zeros only, not matter the eye/frown movements. 

I noticed it's the same when I extract the data in C++ at a lower rate. I also noticed that frown movements are "simulated" in the sample scene of the unity sdk.

Does anyone have the same problem ? Is it a known issue (i didn't find anything on the forum) ?
