Delivery Block

Hi,

In the delivery blocking reasons(SPRO,sd,basic functions, TOR,block quantity confirmation in delivery blocks(ovz7)). Here I had seleceted the delivery block and checked the box for confirmation Block and assigned to the sales document type. But still in the sales order, it is showing the confirmed schedule lines. In va02 in schedule lines i donot want confirmed schedule lines. But here why it is showing still the confirmed schedule lines?

Thanks
