CSV > Item Fulfillments horribly broken

We're still trying to get the item fulfillments via CSV feature to work properly.  We waited a bit for 11.0.3 to stabilize, but when we tested it today, once again we found it to be broken and buggy.

The item fulfillments are created and attached to the sales orders but
[INDENT]1) The tracking numbers we provide aren't used; NetSuite generates its own.  (This despite the 'T' / 'F' setting for label integration in the csv file.)

2) As if the incorrect tracking numbers weren't enough to make this feature useless, we're also seeing sales orders with heinous status problems afterwards.  Sales orders with fulfillments attached are shown as 'Pending Fulfillment' (not even 'partially fulfilled') and in one test case today, we had a sales order that was shown as 'Pending Fulfillment' but had no Fulfill button anymore.[/INDENT]
