When I calibrate my Kikr with my Edge 820 it instructs me to do the spin down test, which works. However, when try to do the same calibration test on the 955 I receive an error. In addition when I look at the list of connected Power devices on my Edge it only lists the Wahoo Kikr once. On the Garmin I have 2 entries for the Kirk - a "Trainer" and "Power". Is that normal?
