Welcome khalid
I’m not on Apple or Logic, but this tutorial might provide some insights. Steps for Setting up Multi Voice Output In Studio One using Kontakt as an example - Tutorials - Scaler Plugin - Community Forum
I know in Studio one, if I enable multiple Kontakt instruments, I need to build one track per instrument/patch (but only one instance of Kontakt), set the midi channel on the instrument AND set the mid channel on the Scaler Instrument Input line. Each track shows both the instrument providing the sound and the source providing the input (in this case Scaler)
Good luck
