@KaitlynMM Welcome to the Fitbit Community! I recommend performing a restart on your One (check @Odyssey13's post)! That should fix those issues. If you need to recover any of the lost data; you can always manually log an activity (check @GisselleM's post). That will credit you with accurate data.
Hope this helps. Let me know how it goes!
