Hi Jesse,
What I've found out recently is that if you want to import cash invoices to AP vendors, you should be doing this in Payables and not BankRec. One other site ran into this very scenario. Importing Payments in BankRec is designed only for misc vendors not in Payables. Apparently there is code built into BankRec that posting imported Payments batches writes particular accounting information.
I believe the vendor number that is available in Import Payments in BankRec was put there to allow reading the vendor name from the master record. But my suspicion is that this has led to problems such as what you have wrote here. From what I found, the next release of BankRec (whenever that will be) will have the vendor number removed from the Import Payments template, so you won't run into this situation again.
This is what I know from R&D.
