kugelmeier Hi. Thank You for the access. I've investigated this issue and as odd as it may look the "P" is a shippment option:
So there is not much we can do since Shipments are coming directly from Virtuemart, so You should ask them to help with it.
BUT if You wish not to show shipments (I believe so, since it's showing P instead of shipments) I would advice to edit file /html/com_virtuemart/productdetails/default.php and remove code:
if (is_array($this->productDisplayShipments)) {
foreach ($this->productDisplayShipments as $productDisplayShipment) {
echo $productDisplayShipment . '<br />';
}
}
