Modify callsign

[F6EXV]

Hi all
I am trying to modify a (busted) callsign in the TX7N log.
When I want to save the change, Log4OM tells me "QSO not saved. Check band/mode/callsign/date"
All these fields are correct, I see nothing wrong.
I have tried to go through the QSO manager section the QSL section, no way...
What is the procedure to modify a callsign already in the log, other than deleting it and entering it fully with all details again... ?

Double click on QSO

In edit window change call sign

Save and apply

Just tested here and it works fine

Hi Terry
It does not work here.
I do exactly what you say, and I still get this "not saved" message...
Using version 2.34.0.0 on Win10.

Had to change time by 1 second, then it worked...
Weird, but problem solved !
