tx count does in address table does not align with address_transactions after delta updates

[soad003]

After the delta updater ran, the tx count found in the addresses does not match

select no_incoming_txs, no_outgoing_txs from address where address_id=887478908 and address_id_group=177495;

no_incoming_txs | no_outgoing_txs
-----------------+-----------------
            4012 |             349

select count(*) from address_transactions where address_id=887478908 and address_id_group=177495;

 count
-------
  4358

this might be a but or an inconsistency in counting transactions with the same sender and receiver.
