[Dxbase] LOTW - DXB difference

[Gary AL9A]

I've never really paid any attention to the confirmed count totals between 
LOTW and DXB until today.  After uploading the 160M CW contacts from this 
weekend LOTW says I have 12,101 QSL records.  I downloaded the latest LOTW 
report file and imported it into DXB.  The I went to the Wizard in DXB and 
in the QSO Filters area checked Confirm = LOTW and nothing else.  I did a 
test run and the Wizard says I have 11,068 confirms from LOTW.  That's a 
difference of 1,033 records between the two!  Any ideas as to the size of 
the discrepancy and where I should start in identifying and correcting the 
errors?
