Bug with displaying date

When we create a popup to edit some data, the date2 field shows an error, where the year is not shown correctly, and the day and month are shown incorrectly.

Can you share a link? Or fill a bug report? Otherwise it’s a bit hard for us to help.

The page is here, it’s on the popup

We need a little bit more to reproduce the issue. Can you set up a page in the forum_app (or in a page in your app) so that we can test?
