Not All Kontakt Instruments Respond to Midi Controller?

Have a Sparrow Midi Fader controller, some instruments in Kontakt (Cubase 14 on Mc) respond to volume sweels, others do not. Is there some meter setting I’m forgetting? Pedal Steel does not respond, a piano does, a string section does not, etc. Just tried the same instruments that are not responding in Cubase, in Logic, and they receive the volume info correctly. What is different in Cubase?
Thanks for any input here.
