Eucon - S4 controlling Cubase

Hi, I have been a long time Cubase/Nuendo user and I purchased an Avid S4 control surface to control both.

When I’m working with Nuendo or Cubase, if I insert an EQ or Compressor on a track, I am able to access it on the Channel Strip Module (CSM) of the S4 (pressing the INS switch). However, when I try to call up a virtual instrument I have in Cubase or Nuendo the CSM’s knobs are completely black as if there was nothing inserted on the Nuendo or Cubase track.

So, I’m able to see and control plug-ins (inserts as EQs, Dyn, etc.) on the S4’s CSM, but Instruments doesn’t show up at all.

Does anyone have this issue?

Cubase/Nuendo most updated version (11.0.20) over macOS Catalina 10.15.7.
