Welcome to the Fitbit Community, @Clh1963.

Thanks for the details shared in your post. I recommend trying the following:

1. Please confirm that your sleep settings are normal and not sensitive: What is the difference between the normal and sensitive sleep setting in the Fitbit app? 

2. Restart your device by following the steps from this help article: How do I restart my Fitbit device? 

3. Try sleeping with the watch on your non-dominant hand if you haven't been doing it already. 

4. Confirm that the watch is snug on your wrist. 

If you want to edit your sleep log, see How do I edit or delete sleep logs in the Fitbit app?

Hope this helps!
