VA is correct its Virginia thats wrong and that probably came from an internet look up, an import from other software or by manual input from the user.
Yes you should use the accepted ADIF abbreviation for both your location and the other stations locations.Do I change LOG4OM Station Information to VA for future and edit all QSOs to VA in log?
If you read the other threads on this subject this is due to the Tqsl update now starting to match state information to the ADIF format
You must also change it in TQSL because that is the real issue, not Log4OM
