Date picker Does not work

I have a contact form with conditional logic, I need to select 2 specific dates with the format D/M/Y and based on that other fields are shown to fill in, when I configure the datepicker with that format and I select a specific date the field is not shown, but when I select the next day the field that should be shown with the previous date is shown.

I don’t know if I am explaining myself well, I don’t have good English.
