MIDI Fighter 3D Script; Live only detects plain MIDI

I’m trying to build a basic script for my MIDI Fighter 3D, but it seems like no matter what I do, Live only detects its input as plain MIDI. I’ve used MIDI learn in CSS to map out the buttons, I’ve set up stop, play, session record and arrangement record for the first four buttons, just to try it out. The script installs successfully, and shows up in Live. I set it to track and remote in the settings, as described, but still, Live only picks it up as basic incoming MIDI. If I turn off “track” in the settings, nothing happens. What am I doing wrong?
