Fitbit Steps to MyFitnessPal Complications

Let me start by saying I'm a bit of a technological caveman. When I first integrated Fitbit steps it worked great - would be consistent from watch to MFP app and would deduct calories accordingly. Now it seems to stay consistent, but with no calorie adjustment. And some days the calories do adjust based off Fitbit steps and other days it doesn't. For instance, this past Sunday I had 7,631 steps register on MFP from my Fitbit, but 0 calorie adjustment, but on Monday (yesterday) I had 19,247 steps register on MFP from my Fitbit and a 990 calorie adjustment. How do I make this consistent every day? Thank you!
