datepicker wrong date format

Hi There,
My client has a gravityform installed on his wordpresss website with a datepicker. In the backpanel it is configured to display the dates as dd/mm/yyyy. However when selected in the form, the date is displayed as (for example) 31 March 2021. Which leads to an error code. After receiving the errorcode and selecting the date once again, it displays correctly. Please advice. thanks in advance.
