S62 suddenly jumps to wrong hole

This happened twice during the same round. While walking on 3rd fairway, S62 jumped to hole 14 by itself. This same happened on hole 5, it showed 14 again. The rest of the round was ok. Any ideas why?

The course data must be correct because a round the day before went with no problems? This kind of behavior is most annoying while you should  focus on your golf ball, not fixing gadget problems.
