NX4 issues

Hi all,
I’ve recently bought an NX4 from Italian Distributor Leading Technologies (order of January 2023), software version 4.8.1240.
There’re some issues with the Sub Playback Fader section… some of these faders get random values when I get them from “X” to “0%” and start to move virtually like 0% to 32% ecc…
I think there’s a problem with the PCB… any help?

Thank you all

Lorenzo
