I have been preparing for migration of existing purchase orders by creating appropriate json and submitting it to the orders/composite-orders endpoint, using the composite_purchase_order.json schema as a model. I have successfully loaded half a dozen purchase orders, each of which contains at least 1 po line with the vendor account assigned. When I bring up the po_line in the Orders UI, the assigned account doesn't display in the Vendor section of the po_line; it appears to be a dropdown, which is not currently functional. I have verified that the po_lines do have a vendor account assigned by doing a get against the orders/order-lines endpoint.
I realize this might not be a bug, just a piece of functionality that hasn't been developed yet. But I wanted to check if that was the case or if this is a true bug.
