We have discovered a glitch in event creation - some events will not show in upcoming events modules depending on how they are created.
The successful method:
Click on your username and select groups. Select the group in question. Select the 3 dots and select create event and follow the process.
The UNSUCCESSFUL method:
Select the small folder icon and group name under the title of an existing event. It shows a blue box with "New Event". Follow the process of creating an event.
If you use the unsuccessful method we observe the following:
1. The process does not ask you to select a category for the event
2. The event does not send out any notifications of its creation
3. The event does not show up in certain modules such as the upcoming events module.
