OK. On next update you’ll be able to prevent these commands to appear in the list by setting quantity to 0. Thank you very much for reporting the issue.
Here is a sample. Sorry for Turkish but all pink items are toppings of ice cream and green button is “OK” button. See how I’m adding ice cream (dondurma) product by choosing toppings (order tags) and click “OK”.
All buttons are custom buttons but pink buttons (toppings) will appear in the list but green button won’t as I’ve set quantity to 0.
