I have Vanguard mutual funds in my Fidelity 401k. I didn't like the names originally provided so I renamed the securities in Quicken to something more readable. For the past several months, perhaps even dating to last year, when I download investment transactions from Fidelity, Quicken isn't matching the transactions to the correct security. If I accept the transactions, Quicken creates a new holding in the account for the original name. I then have to go back and edit the transactions to point them to the right security. Also, when finishing the update, Quicken reports a mismatch in my holdings because it's reading from Fidelity the old name and can't match my actual holding under the new name. The attached screenshot illustrates the problem.
How can I fix this permanently? It's quite annoying every month I download transactions.
I am running Quicken Classic Premier R55.26 on a Windows 10 system.
