AeroPod, PowerPod and Newton

the bike dash software shows up a very strange graphic for cadence sensor as you can see in the attachment.
it goes more down to zero than normal value.
on the bike it does not go to zero that often. and more, it does calculate the good average/maximum.

is there something wrong with the sensor? can I do something to allign the sensor or check when en what's wrong?

Make sure your cadence magnet passes close to the cadence sensor, with the magnet positioned more closely to the end of the sensor where the cable feeds into the sensor. The magnet should pass within a few coin widths of the sensor.
