Shipment charges show in Purchase Order but is not being added to the total

[deejayM]

Virtuemart 2.0.14
joomla 2.5.8.

My problem is this.  The shipment is no longer being added since the latest upgrade of either Joomla or virtuemart.   Everything seems to be set up fine on the products and in Shipment.  In fact the 'Purchase Order' page in administrator shows the correct calculations for Shipment but this amount isnt being added.



Any ideas on what I can do to sort this out would be appreciated.

Thanks in advance
