The number of active kitchens is capped by the Client Config value Max Active Kitchen Locations (default 1); it is set by Sprwt as part of your plan and is not editable from the Configuration page. The list header pill (e.g. 1 / 1 active) and the Add new (Left: N) button show your remaining slots. When you are at the cap the page shows "You have only N active kitchen locations available. To get more please contact Sprwt. We charge $150 (or $500) per kitchen location per month" and a Click here to buy button to the Add-ons page. Inactive kitchens do not count, so you can free a slot by switching Is Active? off on a location you no longer use.
