New User!!!

Upon my initial install of Zimbra Desktop, I was able to enter the 'Preferences' control panel, select the 'Mail' category, and then set intervals for my 'Email Receipt Frequency' which was an option under the 'Displaying Messages' tab. The option for 'Email Receipt Frequency' is no longer visible. The first item showing up under the 'Displaying Messages' tab is 'When I click Send/Receive'.

Is this a bug that came with my recent upgrade to version 7.1.1 or something I have done wrong myself regarding other admin settings???
