Changing date display format adding a year??

[tony_222]

I have noticed something very odd today - I have changed the the display format of a date field in a dashboard and when the data is 2024-12-31 it is adding an extra year and reporting as 2025-12-31.

If I leave the format as "Date (short month name)" it reports correctly but if I use any other date formats, it adds an extra year. I need to change the format so the date fields are recognised as dates when exported to csv.

I have tried changing the format of the raw data which feeds to the dashboard but can't get anything to work.

Has anyone else noticed this/have any ideas on how to fix?

Thanks!
