Hi, I have bought the Forerunner 955 recently. There seems to be a problem with the Treadmill Distance measurement. I walked for about 6-6.5 Kilometers, but the distance on the watch was only 1.06K. The caliberation also was allowing an increase only to 2 Km, not more than that. At this rate the product is useless for me on a treadmill. Do help. Thanks
