Thank you for taking the time to visit the Community to report this issue, although I apologize that you have not received a response.
I would first recommend running the Validate & Repair tool on the original data file from the File menu > File Operations > Validate & Repair option.
In the Validate File window that opens, click the top box to "validate file" and then click OK.
When the validation completes, a data log will open in Notepad, please let us know if any errors or issues are found/repaired, and when ready close and re-open Quicken.
Please let us know what you find!
