Online accounts settings cannot edit or remove accounts

I have a couple of unusable accounts which I cannot use, edit, or delete. When I try to edit them, it just says "Go online to edit your personal information". Unfortunately the whole reason I want to edit the account is because it can't go online. When I try to delete and start again, I click the "Remove Account" button, and a window comes up saying "Are you sure that you wish to remove this Ubuntu Web Account?". Then I click "Remove" and the following message is written to stderr but nothing else happens:

** (credentials-preferences:4037): WARNING **: identity_registered: GDBus.Error:com.google.code.AccountsSSO.SingleSignOn.Error.IdentityNotFound: The identity was not found on the server.
