Fitbit Sense miscounting swim laps

[Ottley]

Hi, I’ve read the other posts about this topic although my problem seems to differ in that my Fitbit sense accurately counts swim laps when I’m doing breast-stroke or front crawl but for some reason double counts the laps when I’m doing backstroke. 
Any way around this?

Welcome to the Fitbit Community @Ottley. Thank you for letting us know about this inconvenience.

There are several ways to record your activities including: Workout mode on your Sense, SmartTrack, MobileRun and manual recording. With the exercise app you can capture real-time stats, including heart rate data, calories burned, time elapsed, and route traveled. To learn more about it you can check How do I track my workouts with my Fitbit device?

Have you checked the SmartTrack auto-recognition setting on the app? The SmartTrack function automatically detects activities involving a large number of continuous movements such as Swimming. You could be using two ways of recording an activity at the same time, this is not recommended as it may cause some information to be missing. You should disable the automatic recognition choice on the application. SmartTrack recognizes exercises that last more than 15 or 10 minutes depending on the settings. This feature may activate at the same time as the exercise application so, I therefore recommend that you disable automatic recognition.

I hope this information will be useful to you.

Best regards !
