MyFitnessPal Deleted Steps from FitBit

I got a fitbit for the first time this week, and it's been going good. I had everything set up to work together and MyFitnessPal was tracking my steps perfectly.

This evening, however, went for a walk, and when I got back and checked MyFitnessPal I saw that the app had cleared all my steps from the day. The "calories earned from fitbit steps" was still there but just my steps were gone.

Has this happened anyone else?
