Polish locale is not using correct date format

[Valdnet]

The month number for the Polish region should be displayed in two digits. The correct entry should be: 24.03.2021 It is not allowed to write as in the screenshot:

Calendar app

Calendar app version: (see apps admin page, e.g. 2.0.1) 2.2.0

Server configuration

Nextcloud Version: (see admin page, e.g. 17.0.2) 21.0.0

Still the case - most likely an issue with moment.js

Hi, I suggest changing the title by deleting the reference to Polish, as the problem is also present in French :

and in English (US) too :

In the settings page, format is ok :

Calendar app version : 5.2.1 Nextcloud version : 30.0.9
