Noted that the shipping rate cost is not properly imported for VM3.
See attached

The shipment_params in _virtuemart_shipmentmethods looks like:
shipment_logos=["tnt-economy-logo.jpg"]|weight_start="12,001"|weight_stop="13,000"|weight_unit="KG"|cost="75,00"|tax_id="3"|
while when saving manually, the shipment_params in _virtuemart_shipmentmethods looks like:
shipment_logos=[
"tnt-express-logo.jpg"
]|show_on_pdetails="1"|countries=""|zip_start=""|zip_stop=""|weight_start="0.000"|weight_stop="1.000"|weight_unit="KG"|nbproducts_start=0|nbproducts_stop=0|orderamount_start=""|orderamount_stop=""|shipment_cost="75,00"|package_fee=""|tax_id="3"|free_shipment=""|
It seems that the "cost=" should be "shipment_cost="
And maybe it is advisable CSVI to fill the missing params also

Would appreciate your feedback.
