Hi.
We are experiencing some issue when we start new sprint. When we want to start new sprint, then the date format warning (incorrect date time format) is shown (near sprint end date). Sprint is not created. I tried to play with it a little and i noticed, that by default it shows AM/PM instead of localized version ("dop." or "odp." for Czech language). When choose the date manually, then rewrite the AM/PM manully to localized version, then i am able to save it.

When i use preset periods (1 week, 2weeks etc.), then it doesnt work at all - i am not able to change/rewrite sprint end date, so it shows the date format warning all the time.

Can you fix it? Or can you give use some hint what to change in our settings?
Thanks.
