Apple Watch SE Not Recording Sleep Data Randomly only Sleep Heart Rate and Respiratory Rate working

This happens randomly, before someone tells me i haven’t set up sleep correctly it works fine other nights set up exactly like this. I set my sleep schedule manually every night and verify that it is in sleep mode when I go to bed. I receive the good morning alarm. When I go to check my sleep from the night it says no data. I also have a few nights it shows I am asleep but it does not break down the data into stages.
