I would next recommend running the Validate & Repair tool on the 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.
If this process does not correct the issue or return any additional details, I would next take a look at the ongoing discussion available here and see if this matches what you are experiencing.
Let us know what you find!
