Number of rotations in Speed Sensor 2

Hello, I have problem with Speed Sensor 2. Namely, total number of rotations doesn't fit inn any activity. For example in 8km ride total number is 86, and for almost 10km it shows number of 602. Is there a possibility to fix this? The distance is correct based on gps measurement. No any other magnets near sensor.

Where are you getting the number of rotations from?

It is in "statistics" tab of recorded activity in Garmin Connect.

This is an activity captured on the speed sensor and then synced to Garmin Connect?

Would you mind sharing the activity file?

Exactly. Without any other sensors.

weird... could you please share your activity? I have never noticed that there is such counterm checking one of my last activities outside https://connect.garmin.com/modern/activity/12140298571 and it is matching average cadence for that time. But sure, I am not using only that sensor, so in such case maybe there is something wrong since the sensor records the whole activity and then it gets uploaded to GC. Would be good to check what is inside fit file.

Hey, after analising in Tool I found something strange. After exactly 13 mins speed was on constant value of 10 km/h till the end. And it shows heart rate with strange values (I wasnt connected to any heart rate sensor). What is more, avg speed on the phone is 20,5km/h and in file it is 14,17 km/h. In the second activity there is same bug, but after 15 mins without seconds.

https://connect.garmin.com/modern/activity/14621338038?share_unique_id=11 - there is an example of mentioned activity. Distance is 8.77 and number of rotations is only 79.
