I've never had this error before…
Are there 'hidden' transactions in a brokerage account in quicken?
My Vanguard 401k today had a set of inaccurate placeholder entries, so I deleted them.
They no longer show in the account itself (either in the main register or in the separate Placeholders tab).
However they still show up in the Holdings view - I see a set of transactions with today's date, and the quantities in the Holdings reflect that.
Also the quantities in the register somehow reflect them. If I add a share to the holding with yesterday's date, the new value doesn't include the amount of these placeholders; if I had a share today, I see the new value does include it.
It's basically behaving as if there are hidden transactions in the Placeholder amounts.
I've tried Validating the file and it doesn't correct the issue. I used the Repair setting not the Delete and Rebuild because I don't want to lose all my price history beyond the 5 years.
