SpectraLayers 9 Pro, How to unmix Piano, Drums and Bass?

With Spectralayers 8 Pro it was possible to unmix Vocals, Piano, Drums and Bass separately. In Spectralayers 9 Pro I can not find these items: ( > Layers > Unmix Stems). Can you please explain me to find these items in Spectralayer Pro 9
Thank you,

If you cannot see it it means you’re running SpectraLayers One. You should activate your Pro license in the Steinberg Activation Manager.

Thank you Robin, it works.
Kind regards, Urs
