New problem (master) stock sell showing up as payment

[Jack]

I just looked at on of my investment account to reconcile the new  
statement, and the brokerage account has a large negative balance.   
Without doing a full audit, it appears that two stock sell transactions  
(for the same security) last month are showing up in the brokerage  
account as Payments instead of Deposits.  I'm know I did a proper  
reconciliation last month, but now those numbers don't match.  I have  
not yet gone through all my saved copies to see when it changed, but  
that's next on my list.

Just in case anyone has any ideas, one of the transactions is below.   
I've trimmed the memo of lots of excess details Merrill Lynch includes,  
and I trimmed the bankid.

   <TRANSACTION commodity="USD" entrydate="2022-07-02"  
id="T000000000000025879" memo="Sale: PUTNAM ULTRA SHORT DURATION INCOME  
FD..." postdate="2022-06-15">
    <SPLITS>
     <SPLIT account="A000345" action="" bankid="" id="S0001"  
memo="Sale: PUTNAM ULTRA SHORT DURATION INCOME FD..." number=""  
payee="" price="1/1" reconciledate="2022-06-30" reconcileflag="2"  
shares="-55723/50" value="-55723/50"/>
     <SPLIT account="A000941" action="Buy" bankid="ID 20220614..."  
id="S0002" memo="Sale: PUTNAM ULTRA SHORT DURATION INCOME FD..."  
number="" payee="" price="-10/1" reconciledate="2022-06-30"  
reconcileflag="2" shares="-55723/500" value="55723/50"/>
    </SPLITS>
   </TRANSACTION>

Account 345 is the brokerage account and 941 is the stock account  
within the investment account.

One thing which caught my eye is that the split for the security has  
'action="Buy"' which worried me more before I noticed that it has that  
value for lots of transactions other then stock sales.  Might that be  
an issue, or is it likely a red herring?

I'll post more when I have a tighter window on when the problem started.
