Hi Dennis,
I updated about 500 QSOs in the logbook and many did not find data on qrz.com and the name field remained empty.
After running the fix.stuff program I noticed that the PFX field was filled with the string 'F4' for all those QSOs missing the name regardless of which dxcc they were. It seems appropriate to point this out to you because it has never happened to me before. Logic 10.0.22 and Windows11.
Thanks 73 from IKØCHU Mauro
