Safari remembers an old phone number for autofill
Safari Version 14.0 (15610.1.28.1.9, 15610), OS 10.15.7 (19H15)
I had a phone number for my old house in Contacts. I deleted that number. The contact shows it not to be present on my mac or my synced iPhone.
When I ask autofill to enter my details in a form Safari defaults to the obsolete phone number every time. This happens when I autofill form the FIRST NAME field on a form. If I click the down arrow in the PHONE NUMBER field it enters the correct number
What am I missing, please?
I have quit and restarted safari, and contacts
