new ofx import problem - duplicate transactions that shouldn't be

[Jack Ostroff]

I've been trying to update one of my investment accounts, and have been  
having trouble with one particular transaction.  I've repeated the  
direct connect import several times, and the transaction does not show  
up in that account.  After finally repeating the import after launching  
KMM from command line in order to see the import debug info, I think I  
may have found a problem with the import matching code.  However, I'm  
not sure if it is really a bug, or if Merrill Lynch has yet again done  
something strange.

Background:  in a different investment account which I updated last  
week (updating and reconciling for March) there was a dividend from a  
particular stock on 3/14 for $9.20.  It turns out I own the same amount  
of that stock in the account I'm working on now, and it also had a  
dividend of the same amount on the same date.   The command line output  
from trying to import that transaction is:

Process on: '2019-03-14', id: 'ID 20190314CA051225670881396', amount:  
'9.20', fees: '0.00'
Looking for a match with transaction:  "2019-03-14" , "" , "-9.20"  
(referenced account:  "Dividends" )
Considering 1 existing transaction(s) for matching
Detected transaction duplicate

If I look at the ledger for that category, I see a transaction for that  
date and amount - and it is a matched transaction.  If I unmatch it, it  
now correctly shows two "almost" identical transactions - the  
difference is that they are for two different investment accounts.

Just to confirm, I did a manual OFX download from Merrill Lynch for all  
dividend transactions for that date, and indeed, there are two - one  
for each account, but with the same FITID value.  I'll call them Monday  
to see what they have to say - but I suspect I won't even be able to  
find someone who even understands what I'm talking about.

Regarding KMM behavior in this case - from the perspective of the  
Dividends category, these do appear to be a duplicate transaction,  
except that they are for two different investment accounts.  Should  
this be something that should block being recognized as a duplicate, or  
is it something I'll just have to live with?

As a somewhat separate question, if I repeat the same import, KMM  
simply says no transactions imported.  Would it not be more accurate to  
say that all the transactions were duplicates?  Otherwise, I never know  
if it really processed all of them, or if something was wrong with the  
import?
