Events not showing on calendar application

Hi.
I created a calendar application. I successfully connected it to an events table named Interventions. I have a form application that enters data in this table, and I can also enter data through the Calendar application. However, data entered using the form application does not show on the calendar. Data entered and using the calendar on the other hand, appears both on the calendar and on the grid and forms connected to the Interventions table.
Am I missing something? I am using SC 8.1.066.
​Thanks

I have similar problems. i could see events first but now events disapeared. it seems there are some undocumented requirements for the fields or data.
