Those are MIDI CC Messages 17 and 19 (General Purpose Controller 2 and 4 respectively). The vertical parameter of Halion’s Sphere Control is by default assigned to General Purpose Controller 2.
I don’t use a Komplete Kontrol keyboard, but you might want to check in the MIDI Assignment Editor that you haven’t by accident set the Play button to send CC 17 (unlikely if the message doesn’t show up in Logic). By default this seems to be sent by Knob 4.
