Colin,
I just discovered that I evidently did something with my log such that the program has gone into my QSL Out column and placed "B" (Buro) flags for QSOs that I don't want to print QSL. Maybe I checked something I shouldn't with the Robot. A great many of the QSOs were already verified by LoTW. The flag has been placed on some QSOs all the way back into the 1970s, so I know I didn't make them purposely.
Is there some way to wipe out the unprinted "B"s without manually going through a log of thousands of QSOs looking for them?
Any idea on how I messed this up?
Thanks,
Lawson
