Fitbit, MyFitnessPal, Strava - double activities

[Roaders]

Hi All
I've just done my first Fitbit activity and is appearing in my feed on fitbit dashboard twice - and crediting me with twice the calories.

I have a fitbit account, a myfitnesspal account and a strava account.
The activity is synced to Strava and from there it's synced to MyFitnessPal (in MFP it has a strava logo). From MFP is then synced back to firbit.

How do I stop this happening?

Thanks

@Roaders Welcome to the Fitbit Community. Thanks for the details mentioned. 

MyFitnessPal will sync logged food and activities to Fitbit and Strava will sync activities tracked with GPS. In this case, you may want to unlink Strava from Fitbit as this will avoid that an duplicate exercise syncs to your account. 

Learn more about the data that will sync between Fitbit and third-party apps in this post. 

See you around.
