I manually edited the sleep log time by one minute and then it recalculated successfully. Nothing else fixed the glitch. 

why would I want to setup my watch as a replacement device?

Thanks for your response, @SunriseRun491.

Setting up a Fitbit device as a replacement device helps in cases where the information is not getting synced correctly.

I'm glad to hear that you've resolved the issue with your sleep tracking.

Have a nice day.
