Often these feeds miss relevant information about locations, timezones, or type of event. Therefore the system is set up to automatically add location and timezone from the group to the imported events. However, it's not possible to add the right category (such as food or film) to the individual events, and therefore the event might not show up when people use the tick boxes on the front page to filter the events.
