OP-z Lfo

Hello everyone
I have been the owner of the Op-z for about 2 years.
When I turn down the volume of a track completely to zero and increase the lfo dept and put the target on “volume” the volume of the track goes up automatically but the volume remain to zero in device settings … is this normal?
I tried to do that with other drum machines and synths but this does not happen.
Thanks in advance

Yes normal.
