Description : If you create an “on-demand” content and associate that content with any of your events. You can definitely see that content under the list view of your Event Catalog page as shown below:
However, you will not be able to see that content under the Date view
This is by design, only Live Presentations are visible in both ( Liste View and Date View )
On Demand Presentations are visible only in List view and not in Date View.
At present this is how it works however in future probably we see some changes in this section as well.
Hope this helps answer some questions,
