Flowbird GO - ANPR Web Portal uses a few types of pages that are used with several pre-defined filters (views). This will cause some columns to be empty and due to the filter used will never contain any data.
An example of this is the "Ongoing Parking Session" view that uses the "Parking Session" page.
Chapters that describe a view on a page only describe to working of the view. The details of the page are described on the list page itself.
You will find a link to that page in the chapter that describes the view.
