ACF Dates and Times - Wrong Format

I’ve just set-up some Heading blocks using ACF Date and Time inputs. The dynamic data is showing but it’s not in the correct format. The ACF field is set to output the data as d/m/Y - but the data on the page is being rendered as Ymd. I’ve tried changing the output to F j, Y but it makes no difference.

How can I control the output?
