I went to add an event to a Joomla website, but wasn't able to add anything. There were fields missing, such as category, description and so on, so I couldn't save an entry. I've attached a screenshot. What am I missing? Should I just uninstall and then reinstall JEvents? In the front end the calendar is under the Main Menu, and in the backend it is under Components > JEvents > Create an Event. I am using JEvents 3.6.5 and Joomla 3.9.21.
