Keylab Essential-61 all notes in legato with Arturiakey Lab V. Is hardware or software problem?

I am new here and I need some help with my Keyborad KeyLab Essential 61 (Black Edition). I am crazy with this.
After playing some notes they stay with reverb souding for much time. It’s as if all the notes were in legato. mode I dont’n use pedal. I just push the “panic” and normalize for a time, but after all this procedure the “legato” happens again.

  1. I plug the keyboard 61 in computer (Mac Mini Pro M2)
  2. I open the software Analog Lab V
  3. I choose some piano sound
  4. I just play some notes
    What’s happen? Is it a problem with the hardware or a software?
