If you are activating an existing account, make sure the dropdown button for that account says LINK. If it says ADD, change it to LINK and select the correct Quicken account register. If it already says LINK, click the button and select the correct existing account register. If you do not do this, then the account will be added as a new account instead of being linked to the existing account register.Repeat this step for each account listed. Accounts which are already activated will not be available to be activated again. They would have to be deactivated before you can begin the process of (re-)activation.Accounts which are available to be activated, but you don't want to activate them can be skipped/ignored/marked do not activate.
