Club prompt not working

The club tracking on my new Approach S60 doesn’t seem to be working.  When I turn the Club Prompt screen to the on position, the tube to the right has a gray color in the top half. When I turn it to the off position, the bottom half of the tube has a green color, similar to the other prompts on the watch.  To date, I haven’t been able to get the Club Prompt to work.  The tracking distance that appears at the top of the screen after each shot is working fine.
