Artist Mix Cubase integration

[MNI]

Hi,
I'm using Cubase 9.5 with the latest Eucon version and it seems that the Solo buttons will light up when I press them but they have no function (i.e. they don't actually solo the track)

Also, when I do solo using a mouse click, the solo button doesn't light up. It turns the "ON" button off for all other channels.

The mute (or "ON" buttons) work as they should except on VCA tracks. In which case I can't press the ON button to mute or unmute, and also whenever I solo using my mouse I get no visual representation on the Artist Mix.

Is this a known issue? Or am I missing anything regarding Cubase?

thanks :)
