Due date "tomorrow"

I’ve been using OF3 on mac & iPad for couple of years and suddenly noticed that when a due date is tomorrow, OF3 (mac) is showing this as the date tomorrow and not the word “tomorrow”. It shows a due date for the day before today as “yesterday” and the OF website shows a screenshot of the projects outline with “tomorrow” visible for some due dates. On my iPad, OF3 shows due dates as “tomorrow”. Is there a way to get OF3 (mac) to show today+1 as “tomorrow” or has it never done this and I’ve just imagined it ???

Bizarrely, today OF3 (mac) is showing tasks due tomorrow as “tomorrow”. Maybe it’s a bug at month end ? I will inform support.
