+ AA6YQ comments below
Dave - I believe I sent you the wrong ADIF file - attached is the one I thoughtI imported and had the issue with. It's first qso is 20200530 and last is 20200531
So it's possible that I did import the wrong file and thus got the double entries
Would you suggest I first deal with and get rid of the double entries and then tryto import the correct ( attached file) ?
+ All of the evidence consistently points to your having imported last year's contest file instead of this year's. My advice is
1. backup your log
2. direct DXKeeper to remove the duplicate QSOs
3. import this year's contest file
