TypeError: calendarItem is null

オフライン
Hi Aras Community, I installed Aras 11 SP12: I am having blank grid screen for all types of view, when opening with an alternative language (eg. Chinese) In the firefox, the console is logging "TypeError: calendarItem is null". There is no issue on this when opening and using the Default Language (English) view. Can anyone guide me in how to fix this issue? Many Thanks!
