Instinct Solar Distance Calculation

Hi, I have had my Instict Solar for a few years.  I do hike a lot and I have a question.   I use the out-of-the-box hiking activity.   When I watch the distance, even if I am not walking it records the distance.   I often forget to pause the activity but I have noticed that it records a lot of distance when you take long breaks and I am NOT walking.   Is there a setting to change this and why is the watch recording distance when I am not moving?  Seems very wrong.   Thanks for your feedback
