2 screen time bugs (im 13 dont judge)

So 2 bugs i have been finding with the screen time that really annoy me is that 1. why does the screen time on my phone go even when im not using it! My parent has set an hour on my phone every day and that hour goes while im at school and the timer should stop when i turn my phone off. And the 2nd thing is how do i fix my phone to turn off the screen time when changes have been made and they are not applying. My parent has turned off screen time and yet it is still on my phone and on the parents phone it says its disabled.
