Today my sleep, duration Was different. It did not differentiate between REM deep light sleep and awake. Is this change permanent? I don’t like it.

You got what Fitbit calls Sleep Patterns (Awake, Restless, Sleep), which get returned when the Sleep algorithm is unable to return Sleep Srages (Awake REM, Light, Deep).

This typically happens when the Sleep algorithm  is unable to reliably measure Heart Rate Variance, so you probably didn't get Heart Rate Variance or Breathing Rate heart metrics returned either.

This happens at times and it's not a big concern, unless not getting sleep stages and heart metrics returned on a regular basis becomes an ongoing trend.
