How to avoid double counting steps please? – Sync Solver - Fitbit to Health Review

Dear Developer: when synced to my iphone it seems to double count steps. You made a comment in an earlier review about how to fix this — but iOS seems to have changed where / how to change the priority of the Health data. How do I do this please? I can’t find the Heath Data in the Health app to change the priority. I am using iOS 14.4 (the Latest). Also is there a way to undo the impact of the erroneous sync? Thanks, Carl
