I have just bought a new helix lt. Is the preset knob supposed to click like the joystick? I sometimes have to push it 3 or 4 times to get it to work. When i push the joy stick, it is set up off the helix and works with 1 push. The preset knob sits right down on the helix and I need to push multiple times to get it to change the lcd. There is no click when I push it, it seems like it is set too low to work properly? Are both knobs supposed to be set at the same height? It seems like something is not quite right with my preset knob! Thanks Much!!
