Watch and phone not listed as data source for sleep

Hi all

the topic is as above. Devices are listed as devices for counting steps and heart rate but somehow only sleep is missing. I have tried a force restart on phone and watch. Deleted sleep schedule and focus and set it up again. I have confirmed that on Watch in sleep app sleep tracking is in on and it’s linked to the sleep focus. The only app that is listed as source for sleep tracking is zeeplife…

My questions are:

1. How can I add Watch to the list of the source devices?
2. How to remove that zeeplife from this list.(App is deleted from the phone)

I would be extremely grateful for your help

BR
