I bought the following module. It has live preview too.

In this video, you can see that when user presses OK, the kitchen order get empty on next return.
The problem I am facing that when I press OK, I still get all the items in kitchen order. Now when I have to provide just the latest items to my kitchen staff, it prints all the previous items too.
Help me with this.
