[otrs] otrs upgrade to 2.4.7 from 2.3

Hello, i upgraded recently and when i look under "Ticket" i have no option to resizethe ticket view (small, medium,preview). On my test system i do however. please see screenshot for the two different systems and how they differ. http://yfrog.com/4botrsj if i click on Status View i do have the option. Anyone know why it wouldn't be shown under ticket/queue view? Can someone also clarify what AgentTicketQueueTicketView.dtl and AgentTicketQueueTicketViewLite.dtl are. my test system only uses AgentTicketQueue.dtl. thanks for any help. Neil
