MFP to Fitbit - Calories consumed not matching

Problem is mine are all in one summary in Fitbit so I can't delete it? It's done it the last couple of days and if I delete the total summary say for example, "breakfast" it never pulls the data through again. Trying to decide which is worse - showing too many eaten or not enough. Really annoying though, almost feels like Fitbit doing it so you will use their food addition, not a chance of that when I've been using MFP for years and have all my foods saved etc
