How 2 Turn On Excl or Choke group in Groove Agent SE4

PLEASE HELP WHY DID IS FINDING THE CHOKE GROUP FUNCTION SO HARD? ON GROOVE AGENT ONE IT WAS VERY EASY. I HAVE SELECTED MY SOUND 2 ASSIGN AS A CHOKE GROUP THEN CLICK ON THE (E) AT THE BOTTOM WHICH SHOWS ME THAT EXCLUSIVE IS OFF NOW HOW 2 TURN IT ON.
CHEERS

Select the pads that shall choke each other,
go to Edit > Main. Above the Waveform-Window of
the Sample you see the max. voices and the groups.

Mind if I resurrect this?

I have done exactly as stated:
Select all pads, go to Main, set Excl to 1 and Poly to 1 for all pads.
It’s still not working! No notes are being cut off, not even from theirself let alone from other notes.
Has anyone else had this experience? It worked fine for me until recent…

This seems to be sort of a bug of the SE version.
