Traktor pro 4.1.0 Gain reduction meter missing in Ozone Maximizer preference settings

Hi, I have been struggling with the Traktor pro 4.1.0 Gain reduction meter, it's missing in the Ozone Maximizer preference settings. Any ideas on how this can be resolved? I have tried reinstalling Traktor, I'm using an S4 mk3 in internal mixer mode, OS windows 11

Many thanks
