Amps issue

I’ve purchased Amps recently, and I’m having an issue with envelope signals. The module is not responding correctly to the envelope. After receiving the envelope signal (from Zadar), the sound from the VCO leaks. I tried the other VCA (tangle quartet), and it works well; there’s no bleeding, so I guess it’s Amp issue. Does anybody have the same problem?

Hey, do you think you could send a video to Thanks!
