Problem

While using German or French as the user language, the date picker for version releases is corrupted.

Steps to Reproduce the Problem

1. As a user, go to User Profile and change the language to German or French.
2. Go to a Scrum board.
3. Click on Releases
4. Click on the ... button for any version.
5. Click on Release.
6. Click on the date picker to choose a date.

Expected result

The release should be created

Actual result

There is an error that the date format is wrong:

Workaround

• Use other languages to select the date for the version release, as this Bug is not affecting other languages like English and Spain
• Set the release date via Project Settings > Versions page.
