Investing window shows negative shares of a CD already matured. version 2013

Security detail correctly shows it was bought 3/7/19 and sold 3/10/21, shares held = 0.
Holdings window also incorrectly shows negative shares of the CD.
I can't delete the security (has been used in a transaction).
Transactions properly shows sale of security, CD purchase is not in Transactions.
Alll account balances are correct. Security purchase in my checking account, but not purchase.
The purchase was probably from an old closed account.
Executing file ops > Validate & Repair:
Validate caused "Quicken not responding" after checking transactions for broken transfers
Rebuild investment lots showed no errors.
How can I correct this issue without affecting account balances?
