Drum set sounds (auditioning and moving)

Two questions:

1 When I click on the kick drum (selected in the attached pic), I hear the hi-hat even though the name of the selected drum appears (e.g., “K.Dr.”) How do I hear the drum that I have selected and clicked on (to audition)?

And … when moving the pitch/drum sound up or down with Opt-Up/Down arrow keys, the sound doesn’t change even though the note head moves with the key command.
