Screen time on iPad

My iPad mini 6th gen (bought in early 2022) is TRIPLING my screen time. I thought that I had it so it was showing my phone and iPad screen time together but it’s just for my iPad and it says almost 35 hours of screen time even though the bar graph for the day shows MAYBE 10.5 hours. It didn’t show any screen time at all for a year and a half and then it was accurate for a few months but now it’s showing impossible numbers. My total for this week is almost 200 hours for 5 days. It also has my phone’s screen time at almost 35 hours but on my phone it says eight hours. It doesn’t really bother me because I don’t limit/pay attention to my iPad screen time but it’s just really confusing.
