Planner Task Due Dates Note

Planner Task Due Dates

I've been using planner for a few years at work amongst the team. We are each assigned to tasks with information and due dates. As of recently, if a task is due today (let's say September 18th), it will be in the "Past Due" bucket whereas it used to be in the "Today" bucket - this is when filtering by Due Date.    Any thoughts? Thanks!
