[WriteLog] SS ADI prefill not updated for duplicate QSOs

[Mike Heideman]

While reviewing recent Sweepstakes LCRs we discovered a duplicate QSO that had been marked as a busted QSO by ARRL.  The callsign was in the ADI prefill with a precedence of Q.  The first QSO was logged with a corrected precedence of A.  The dupe QSO was logged with precedence Q, apparently due to my inattention to what was actually sent and that the prefill continued to use the ADI exchange information instead of the corrected exchange from the earlier QSO.
In this case it didn't affect our score since the first QSO had been correctly logged by both stations so the second QSO would have been flagged as a dupe instead of a busted QSO if it had been error-free.
If the first QSO had not been logged by the other station then we would have lost a QSO due to the prefill/inattention.  In other contests when stations can be worked on multiple bands or modes then the ADI prefill is overridden after a QSO is logged with a differing exchange.  It would be desirable for Writelog to similarly override the ADI prefill to prevent errors in duplicate QSOs during SS.
It was a shock to me to see that a duplicate QSO affected our reported error rate and then to realize that our score could have been reduced for a miscopied duplicate QSO.
