Screentime tracking goes haywire the next day

[xoteaa]

Have you checked it on Project Progress ?
Yes

Describe the bug
Screentime tracking works perfectly fine on the present day. But on the next day when you try to look at the previous day's screentime it's completely messed up. A bit of your actual screentime gets reduced and then gets artificially increased massively by Mindful itself.

To Reproduce
Steps to reproduce the behavior:

1. Go to the statistics page.
2. Click on a previous days stat

Expected behavior
There should be no difference in the data we see today and on the next day when we look back.
