I would recommend deactivating the account in question. The steps to deactivate are available at the link below.
https://www.quicken.com/support/deactivate-online-banking-services-quicken-accountI would then reactivate the account using the steps below. This process acts as if a new account will be created however this will not create a new account but give the option to link all of the accounts at once.
Please let us know if the trouble persists after completing this step.
