Some users encountered this problem:

After you added an event, it does not show up in Calendar view, but in in list view.

Solution:

Just go to View Options, and update with the default settings will do.

So, it is always recommended to check the following two pages to make sure the module is properly configured:

1. View Options
2. Main Settings

If you are not sure what to change for now, just save it with default settings.

Thank you.
