Line items were initialised with undefined quantities which makes it impossible to distinguish between the initial unset quantity and a user entering an invalid quantity. When a user changed order cycles, all quantities are reset and the UI displayed the quantity modifier buttons instead of the Add button. Initialising with the valid quantity 0 helps us to display the Add button in that situation.
