Date field not working correctly?

Hi,

I made a for and added it to my website. https://www.familieshoot.nl/contact

When you want to set the date and click the date I get a error Deze datum is niet geldig. De datumnotatie is {formaat}

I am not sure what I did wrong? 

here is a screendump of the page .. I select the date and nothing happens.. then I click outside the selector and then I get this error. Selecting the date does not go back to the form

I tested your embedded form, but I was not able to replicate the issue you reported. The Date Picker widget is working fine on my end.

Were you able to resolve the issue? If not, please tell us which device and browser are you using.

Thanks for your quick reply.. I changed the date selector to a widget and
this one works...
