Your schedule should be placed in the view map and once there check all the settings to ensure the right info is to be displayed. If you then open the schedule via the view map it should display consistently.
My pet bug at the moment is under navigator where it displays the layer combination setting as "N/A". This is not true, you need to have the right layer combination assigned to ensure the elements are displayed. This also includes turning zones on if you want to the associated room names to appear in your schedule.
