You will need to press save for each of the new items created or edited. A status of "Current" means such item is active, whereas changing the status to "Voided" will simply void the item, meaning that such item will NOT be calculated towards the total number. To check the items saved, go to

localhost:3000/items

The data is saved on the server side. No database was used (for now).
