I’ve got the same problem with some Date picker fields and it’s fixed making an if for each one.
On the other hand i would like to tell you: Lot of thanks @maira!
You helped me to fix another problem showing Date picker fields.
It was showing current date even when the fields was filled, and in another use it was rendering a different date from the one saved on the field. I was going craczy, but tried your way to make the date_i18n (different from the one in the ACF documentation) and it works perfect!
So, many thanks!
