Volca FM Voice Stealing (click noise)

Hello guys has anybody experience that problem with volca fm especially with arp running, its sounds like a harsh click sound giving the impression that envelope is retrigging
i have found only this case:

Could you please advise if its normal or bug or whatever because its so annoying it happens to me with all voice settings or even just pressing keys.

Thanks!

One of the reasons I have come to not trust korg anymore.
