Selecting From Multiple Addresses
If an entry was imported from Contacts, and has more than one address stored in Contacts, a blue “badge” will be shown beside the currently used address. If you are running Big Sur or later, the badge will show the number of addresses associated with that person.
To select an address, just click on the badge and select the address from the popup. Close the popup via the red close button on the top-left of the popup.
