Blackshark V2 - Changing the volume also changes audio balance

Hi,
I'm having this really annoying problem when I change my headset volume (by using the keyboard or the windows settings) also changes the audio balance.

So tapping volume up will make the audio unbalance, tapping few time on volume up/down will even the balance again.

Does anyone incounter this problem?
The headsets are brand new, also the PC.
All drivers are installed correctly and up-to-date.
