Missing data if sleep time changed

It happens quite often that the Vivoactive 5 records the time of falling asleep incorrectly, sometimes with discrepancies of several hours. The problem is that when you manually advance the sleep start time you end up with missing data.

During this manually added period, we do not have data on sleep phases, movements, or HRV. The sleep score is distorted.

Well, that makes sense. If you're moving the start time to an earlier period when it wasn't recording that data, then it will be missing. If you were moving the start time later then I'd expect it to be there as it was recorded.

Maybe it's logical, but I didn't have this problem with my little Venu Sq. I have the impression that we're going backwards in terms of the quality of sleep data.
