How To Remove Accounts from Update Screens

When performing an update of all my accounts the first screen that appears includes a reminder of institutions that need re-authorization before those accounts can be updated. For me this includes one credit union and one investment house. I no longer do business with either, therefore, no need to update. I have kept both companies' registers for historical reasons, but have no transactions nor active accounts with either. These same two companies appear on the second window where we have the ability to select/de-select which companies to update. They have been de-selected there for over a year. I've looked everywhere and can't find how to remove these companies. in the two update screens.

How do these institutions get removed from both screens?
