Joe,
No ... there is not anything you need to do with any files. I have scanned the Log4OM V2 Release Notes and as best I can determine this was corrected in Version 2.3.0.0
That being said, I've also put a question about this to our Alpha Team to help keep me honest ...
I also went to QSL Manager to do downloads from Eqsl and captured screen clips of my first download (with last download date noted) and then I restarted V2 and did the same routine and captured yet another clip with the refreshed download date. I've attached the clips below. Neither of them reverted to a 2019 date.
If you are still experiencing this can you capture some screen clips and add on this thread with any other additional information?
