We have a Published Sheet that displays on a large monitor.
Up until recently, the sheet displayed the Gantt view.
In the last several weeks however it is displaying the Grid View.
We can change the view on the monitor to Gantt however when
the sheet refreshes it goes back to Grid View. I checked the
Publish Settings and the options seemed to possibly have
changed. The Default View options are shown below:

The Grid (Gantt) View are now combined which doesn't make any sense
as these are two distinct views.

How do we get the Published Sheet (exisitng url) to display the Gantt View again?
