Bob, N7FQT, offered a good suggestion or workaround for your issue.? Another way is to export the ADI file prior to upload and use a third-party software such as ADIF Master (Free) to verify the call sign and operators.? Once you make those adjustments, import them back.? Another, more simpler way, would be to use bulk edit and define the fields you need to change for the records you need to change.? Outside of that, it seems like an issue with club members, or scouts, not knowing the procedure.? For that, you could leave a note.?
Our club has similar issues as we do a lot of events with a mobile trailer and multiple ops not logging in or out even with someone pressing CTL+S before they change.
Just some ideas.
