I upgraded from Quicken Classic 2013 to 2019 on Windows 11 at the end of March. Since then, I have entered new transactions for April. I close the software and open it again and things look ok. I open and close my main QDF file and a second QDF file that I have for a separate set of accounts. After 2 or 3 times opening and closing, I open the main QDF again and my transactions for April are now blank!
The blank transactions cannot be deleted. I ran a Validate and a Super Validate on copies of the file and that erased the blank transactions so I am back to the end of March and have to enter the April transactions all over again. The April transactions seem to be "remembered" in the auto-suggest when I input them again. These are transactions in a bank account or credit card account. The other QDF file does not experience these problems, although it has much fewer transactions in total. My main QDF has all transactions going back 25 years, while the second one has maybe 8 years.
I had it in a linked Google Drive folder, but moved it to my C: and that has the same problem. The second QDF is working fine from the Google Drive folder.
Not sure what to do next. It just took me a few hours to catch up and now I'm back to square one.
