Datepickler shows wrong date in time period mode
This happens when we enter first time data to the calendar field in the entry. Let say today is 16.11, in the 'date from' field we set for example 18.11, this will set date for this field and automatically change date of 'date to' field also to 18.11, but when we open datepicker for this field, there is still selected today (16.11).
