[GNC] Accounts Payable payment entry is marked as an Invoice

[Adrien Monteleone]

I was entering annual property tax bills, and noticed for one from last 
year, that it has a notation on the Vendor Report of:

"Please note some transactions were not processed
1. Transaction has type invoice but no owner or lot"

Viewing the AP register shows the payment entry, but marked with an "I" 
instead of a "P".

Jumping to the Invoice shows it as PAID, and viewing lots shows both 
invoice and payment with a zero balance. (no balance really)

Any ideas on what caused this and how to fix it?

(using 4.7 on BigSur)
