Diary print out wrong times

Hi My receptionist was on the phone to you Monday about this problem, but have not heard back so I’ll put it here.
I have main clinic with 20 min sessions and a secondary clinic where one person works 30 min and another 20 min sessions.
Since the latest update we can only print a diary with time slots of 30 mins. This is causing serious problems as the main 20 min diary is unreadable. We use the diary print out all the time.
Please update me on how you are doing with resolving this. Thanks
