Automations triggering ahead of schedule

We have been noticing items on our ToDo lists we use are disappearing as if someone checked them off. We have finally narrowed it down to an automations error.
We have it set to change the date on items every night at 11:59 if they have not been checked off. What would cause this?

In these pics I show one example where I had to change it back to today’s date. Also attaching a screenshot of the automation.
