question

I have an item in my inventory which has a fixed price of $1.50. When I add the item twice in the register app, it shows the price as $3.00. Then I open my custom merchant tender app and use the IOrderService to retrieve the order. When I extract the LineItems and print it, I see Water printed twice. Doesn't the sdk group them together?

Here's the response:
