I experience an issue with the 1Password suggestions. It is not completely up to date with 1Password. Old items are still available but when I select them, it auto fills another account for this website (that is up to date)
So the item I select is not the item that is filled into the form.
For example https://paw.cloud I updated one of my credentials to another email and after that deleted that item deleted from 1Password. But it is still showing this item with the old email address on my keyboard and in the full list (see screenshots)
(I know iCloud is still active but you see it is in 1Password by the subtitle)
And when I select the fressh one it auto fills the sissing one.
