How to import only LOTW QSO's that are NOT in DXK?


trying to sync up LOTW and DXK log, and when i do get lots of QSO's that ARE in LOTW log but NOT in the DXK logs.
i get many "no matching QSO in log" in the LotW_QSOs_ADI_error.txt file. 

how do do an import of all QSO's that are absent in the DXK log but present in the LOTW log?
