MEMS Studio: Failed to parse log file on IR Algorithms Tuning

I'm using a STEVAL-MKI109D with the IR sensor STHS34PF80 and I need to fine tune it to detect objects with low IR emissivity, but everytime I want to load the log file into the IR Algorithm Tuning, the same error appears "Failed to parse log file". I've tried modifiying different things from the log, but everytime, I get the same error. Here is an example of a log file:

# STEVAL-MKI231KA (STHS34PF80)

time[us],t_object[LSB],t_object_comp[LSB],t_ambient[C],t_ambient_shock[LSB],t_ambient[LSB],t_ambient_shock_flag,motion[LSB],presence[LSB],presence_flag,int_1
638,-614,-614,23.470,0,2347,0,0,0,0,0
638,-671,-671,23.540,0,2354,0,0,0,0,0

4754121,-617,-617,23.510,0,2351,0,30,30,0,0

Any idea on what could be happening?

Hi @RVM ,

Thank you!

We cannot reproduce the issue in 2.2.0. Loading the file into offline data analysis page we detected a timestamp inconsistency due to duplicated timestamp on line 4 and 5. To fix it, one of the lines shall be removed. Once done everything should work as expected.
