I've encountered a strange issue with the Calendar application when my system language is set to something other than English — for example, French.

When I try to create a new event, the hour selection behaves incorrectly. Instead of showing the expected hour numbers (e.g., 00 to 23 in 24-hour format), it displays the same incorrect number for every hour slot. For example:

All hour entries show “53”

After restarting the app, they all show other numbers, such as “40” or “33”.

This makes it almost impossible to set the correct time for an event.

I've attached three screenshots that show this behavior clearly, with different incorrect numbers appearing after reopening the app.

Just to clarify:

This issue only occurs when the system language is set to a non-English language.

I’ve tested with French, which also changes the time format to 24-hour by default (which I actually prefer), but there’s no visible option to toggle between 12h and 24h formats. That’s not a problem for me, just something I noticed and thought worth mentioning.

Has anyone else experienced this? Is there a known workaround or fix?

Thanks!
