Syncing with MyFitnessPal, Strava and Fitbit

[SunsetRunner]

I have strava linked to my fitness pal and mfp linked to fitbit.My query is that when my bike ride synced to mfp I checked my fitbit account and it was added there as well.When I looked into the ride on fitbit it said the calories were part of my daily account so far.When I checked in mfp on the calorie adjustment it had the calories including the bike from fitbit and the calories from my bikeride added to the mfp.I may be mis understanding this but it looks like they have been counted twice,I'm hoping someone can clarify this for me as why did it add the exercise to fitbit,thanks

Welcome to the Community @SunsetRunner! This is really interesting. Once you log your activities on MFP, the information is transferred to Fitbit and you get your calories adjustment based on this. I'd like to know if you're manually logging your activities in your Fitbit account again. This could be causing this discrepancy. (just to make sure)    In the meantime, you can unlink and re link your accounts. 

Looking forward to your reply.
