Apple Watch sleep data

Hi Community, looking for some help with my new Apple Watch. I’ve been trying to solve this for the last couple weeks. Question: I’ve set my sleep up and it appears to be working, I go into my health App summary and sleep is there, I click on sleep and it shows my weekly, monthly & yearly average but not my day. I would like to see my REM etc but can’t. I click on show more sleep data and it shows the same information. Any help appreciated. Thanks
