datepicker with blank square instead of Date

Hi all,

I do not understand why this datepicker display a blank square and not the real date on compact mode ... in debug, the datepicker is not null but with the good value (date)

when I click on, the date is available...

If I change the date, the display is fine after....

why in viewwillapear, the date picker show a blank square and note the real date???
