How to turn off automatic dark mode with new OS update

How do I turn this off? In the Reminder app, the buttons that you press to save changes or cancel changes have white text on a white background. I can't find a way to change it in the settings.

It's in black if you have Power Saving enabled. IF you switch that off, the white returns.
