Sleep/Health app goes to Sep 2023 by default

Every time I open the Health app on my phone, the sleep shows Sept 2023. It doesn’t do this on my iPad and I can’t figure out why the difference. It was showing Nov 10, but I deleted all the health data and now it shows 2023. In one thread, they talked about a date in the profile, but the only date in there is my DoB. Another thread said to delete my sleep schedule, which I did and I also deleted the schedule history, but I can’t get it to open to the current day. Do you know how much you have to scroll to get from Sept 2023 to Nov 2024? And it gets longer and longer every day. Nov 10 is the date that I activated my new iPhone 16 and that’s the date it was going to. Can someone tell me what might have happened and how do I fix it?
