Calories burned show 1 day off

Could post the screenshots of the all day HR screens (https://connect.garmin.com/modern/daily-summary/2023-11-25/heartRate, https://connect.garmin.com/modern/daily-summary/2023-11-26/heartRate), and of the Calories Report (https://connect.garmin.com/modern/report/41/wellness/last_seven_days) 

The Calories match well with the HR data: on 26th you have 685 Active Calories (not sure where you saw the 9 Calories), and the HR is indeed quite high during the run, and also later in the day. In contrary, on 25th the HR is rather low during all the day, so it is not at all surprising that there are only 224 Active Calories for that day. So far it looks all right and consistent to me.

Unlike what you wrote in the OP, the 685 Active Calories are recorded on 26th (the day of your run), and on 25th there are only 224 Active Calories, not 685, as you wrote. To me it looks like there is no problem.

thats interesting. Looking at the online version it shows 1 day off from the app version

The screenshot I posted is from that URL that you provided

OK, I see, I was confused by the missing graphs. Check whether the date and time are correctly set on the computer, and especially verify the Upload Time Zone in the User Settings at https://connect.garmin.com/modern/settings
