1.4.2.3 How do I delete stock on a modifier option
To delete stock entirely from a modifier option, do the following:
Click Your Menu > Modifier Option Stock.
Find the Modifier Option you would like to edit the stock of, to the right (You might have to scroll right) click Edit button.
Click the Delete button at the top right. If there is no Delete button appearing, that is cause the Modifier Option has different Initial Quantity and Current Quantity. These need to match exactly that same. Follow 1.4.2.2 How to adjust menu item stock.
A prompt will appear, click the Confirm button.
