💡 Background and solution
The WeekPicker is currently using DateHelper.GetWeekOfYear(DateTime date, DayOfWeek firstDay) for the calculation of the Week number. DateHelper is using the InvariantCulture.
FirstDayOfWeek of the InvariantCulture is Sunday
For example, for de-DE culture, the default value of FirstDayOfWeek is Monday
Additionaly CalendarWeekRule of InvariantCulture is FirstDay
For de-DE it is FirstFourDayWeek
those differences result in different Weeknumbers for both cultures.
For Example the 3rd April 2023 is Week 15 for Invariant and 14 for de-DE
To resolve this Issue we can use the CultureInfo Property of the DatePicker
Another Issue with the german Culture is the Translation for "Week" it contains an 'h' which is also a reserved letter for the time format and will be replaced with the current hour.
The fix for this is to escape the string with quotation marks
