Selecting track/instrument for modulation setup in macros

Hello

How do you select the target track/instrument when choosing a destination parameter for the modulation setup in macros? This is where you use a CV source or expression pedal and is accessed by [FUNC][KIT] > Control in 1 mod, for example.

It appears to default to BD and sometimes I get SD but I don’t know why and I never get the other instruments. I’ve tried selecting the instrument with [TRK][PAD]
