I cannot set my arrival or departure date

This is a visual bug on the profile page. The dates are always shown as 2023-08-31, even though they are correctly saved to the database.

You can cross-check your profile page (https://engel.mrmcd.net/users?action=view) for the correct arrival date, or if you are so inclined inspect the presets on the text inputs in the HTML source code of the form.
