Purchase Order Confusion

Hi All,

I am confused about something with Purchase Orders.

I have items that we stock and also drop ship.  They are listed as regular inventory items in the system.  Today, I am working on a stck order from the vendor.  Each item that I add to the purchase order brings up the name of the last customer who we ordered any of the vendor's items for.

For example, we sent a drop ship PO to the same vendor yesterday to be shipped to Customer A.  Today, I am creating a regular PO (non-drop-ship).  As I add items to the PO, they bring up Customer A's name and make themselves billable every time.  I delete the Customer name from each line.  Even after I have deleted the Customer's name from each line, Customer A's address is available in the ship to field.
