MIDI CC automation - How to only affect 1 instrument at a time?

Diyar

Hello! I'm having three problems regarding mapping MIDI CC automation via my MIDI controller, and I'm wondering if they're related.

Problem A: My MIDI controller affects all instruments at once. For example, I want to use the mod wheel to control the Dynamics knob on two separate instruments - the sax and the trombone. However, I obviously don't want the automation from one instrument affecting the other. How do I control the dynamics for each instrument separately with the same mod wheel?

Problem B: The Dynamics Pattern from one instrument affects the other, despite them having different Dynamics Patterns. This image illustrates what I mean:

Problem C: MIDI CC#1, which controls Dynamics (I think?), does not work at all. When I attempt to use it to record dynamics, it simply does nothing. I've mapped dynamics to an empty slot, CC#24. Does that affect anything?

I apologize if these are basic questions, but trying to find help for a specific problem seems nearly impossible. Help would be greatly appreciated!

Specifically which Kontakt instruments? Separate instances for each in instrument or single instance for both. What midi controller? Is the controller set to transmit on a single channel or Omni? Mac or Win (not that it would be the cause of the issue, just good practice to mention your OS and DAW when asking a question!!)
