I assume @Grizzly62 your manually entering the data through the Fitbit app on some type of device, or through the web, after the fact and not through the Blaze.
May I ask on what device you are entering the data?
Best AnswerI enter the information on a iPhone 7, I have had this phone for a year and entered the info daily never had a problem till last week
Best Answer@Grizzly62 A bug appeared in a recent Fitbit app for iPhones update that is causing this problem with manual logging.
