I'm on Quicken Classic for Windows, Version R65.29, Build 27.1.65.29. The problem started recently, no more than a couple of weeks ago.
I have an investment account that shows a Cash Balance of $470,550.92 at the bottom of the register. When I click on that, the Update Cash Balance window pops up and it shows the correct cash balance of $77.92. The Total Market Value at the bottom of the register is accurate but the Securities Value is low by the $470,473 (the difference between the shown and the actual cash balance).
The Account Overview window shows the correct securities and cash in the Holdings pane but the wrong amount of cash and the reduced market value of the securities in the Account Status (which matches the register).
I found a case with the identical symptoms back in 2021 that was resolved by replacing Bought transactions with N/A for cash with Add Shares transactions. But in my case, it appears that Bought transactions are correct: they show shares added to the account with the cash subtracted.
Any help would be greatly appreciated!
