Datefield struggle with YYYY

Hi :slight_smile:

I have a strange effect on my datefield. My field has the type “date” and the display “YYYY”. When I click into the field and select my year, everything is fine. But when I click outside the field directly after select the year, there is an error message, as you can see. It only happens on display “YYYY” …
Can someone help me with this issue?
