oddness with blank payee and missing category

[Jack]

In checking for unused payees, I found I have a blank payee (name="" in  
the xml file, so really blank, no spaces, it happens to be  
id="P000854").  I have no idea how this got created - probably during  
an OFX import years ago, as the oldest transaction for this account  
(from the Payees view) is in 2014, and is an investment transaction  
imported from Merrill Lynch, which as caused me all sorts of issues  
over the years.

  At some later point, I eventually want to get rid of this payee, as  
it seems all the transactions listing this payee should really not have  
any payee - they are investment transactions and transfers.

However, in looking at the list, several of the transactions have "***  
UNASSIGNED ***".  It seems these are all transfers between a  
brokerage/checking account and another account (brokerage or checking  
or cash).  In looking carefully at these, they all have a memo.  If I  
remove the memo, the "*** UNASSIGNED ***" disappears from the  
transaction in the Payee view.  I have tried to create a small test KMY  
file, but have so far not been able to reproduce the issue.

I'm not sure if I want to call it a bug, since I don't think the blank  
payee should exist at all, and I suspect that if the transfer  
transaction were missing a payee, KMM would not complain about it  
missing a category.

Any thoughts or comments?
