Group by date option not visible

Dear Team,

On the Discover page of Lotus Notes 9.0 I see an option to categorize my mail by when it arrived—today, yesterday, or by date.by choosing Show > Group by Date, however when I click on show I do not see the option “Group by Date”. I updated my mail template buy it did not help. Please let me know how can I resolve this issue.

IBM Notes 9
Social Edition

Release 9.0
Revision 20121208.0805 (Build V90_CD6_12072012)

Thanks and Regards,

Ajay Sharma

I re-installed the latest template and it was completed successfully, but I’m still not seeing Group By in the Show menu.
