Hello @huntsx & @AnnieB2007
Every now & then, my Fitbit device doesn't track the sleep stages and will only show basic sleep data. Like you, I wear my Fitbit the same way. So, I'm not sure what caused it not to track the stages. I did notice that the most recent occurrence happened when I had an extended time of being awake and my sleep tracking was in 2 logs. Combining the 2 logs resulted in simplified sleep tracking and no sleep stages.
One thing to check is the green light on the back of your Charge 5 and confirm that it is on. The green light is the heart rate sensor and needed for tracking sleep details, like the stages. If it's not on, you might want to check to make sure that Heart Rate in the Charge 5's Settings menu is turned on.
