Group put-away of purchase orders


I have an issue in the group put-away of Purchase orders.

The scenario is: I have a PO with 4 lines. I am able to receive all these line and store at default receive location RECV. During the group put-away, all the PO line items are getting picked from the RECV location with the help of the mobile device. But while performing the group put-away, only 1 PO line item can put into the location, while other PO line item’s work slips out the loop and is shown as closed in the line details form.

Can anybody help me on this.
