How can I prevent Screen Time from misreporting app usage on iPhone?

I’m having issues where Screen Time will add time spent on an app, when that time was never actually spent.

This results in both the average time being inaccurate and time limits set on apps activating prematurely. (Ex: it will suddenly tell me my time is up without any prior notification, and I look at the screen time and random times for the apps will be shown in settings)

I’ve shut off all background activity for the apps under the limits, I close out of the apps when I’m not using them and it still happens. Has anyone else experienced this, and does anyone have a solution?
