Delivery address in PO not cleared?

Hi. I have some users who experience that detail-information of the delivery address of the previous purchase order is not cleared when creating the next PO (address 2, address 3 etc). PO is created from P.reqs.

This does not seem like an SAP-error, but maybe related to GUI, server, cache? Anyone come across anything to solve this? The user in particular restarts the SAP GUI, and when logging back on the delivery address is correct (according to the requisition).
