Keychain Access will not delete some items
I have a few application passwords (not website passwords - these are for an application that requires a sign-in) that I want to delete as the application is acting strangely.
In the past, I would select the items in Keychain Access and use the context menu to delete them. I can do that, but it has no effect even after restarting the computer.
These are items in the iCloud Keychain.
