Fidelity Rewards C/C Transactions Downloaded to a NEW Account

Geo H

I am running a MacBook on Sequoia 15.7.3 with Quicken Vers 8.4.1. I have been downloading C/C transactions manually via QFX for 14 months now. My last download created a new Quicken Account instead of landing on the existing account. I inadvertently selected continue when asked during the download process and ended up with the new account and all of the outstanding transactions. Realizing what happened I deleted the new account in Quicken and all of its associated transactions. Are there any known issues with Fidelity?

I should note that all of the transactions were mine it just associated them with a wrong account.

I just talked to Elan Financial Services, the company running the Fidelity Credit Cards, and they informed me that they assigned a new C/C card number to my account. No reason given why! Now I have to contact all my recurring payment accounts and updated the C/C # on file.

How do I change the account number in the Account Settings for my existing transactions, since I would like to have a history of all my transactions with this Credit Card account?
