Right after opening the 1Password beta and unlocking, all the icons on the "Favourites" tab are the icon of the last favourite. Switching between categories and favourites updates the icons.
This is 100% reproducible
When force-killing 1Password and unlocking for the first time, the first icon starts out correct, then visibly updates to the icon of the last favourite.
