You are talking about the autocompletion cache here, which has no relation
to your Contacts.
Remove individual addresses from the autocompletion cache by highlighting
the entry when presented in the suggested names list (use your arrow key to
migrate to the entry) and then hitting your Delete key before you tab out of
the field. If your autocomplete list contains only a single entry, use the
directions here:

To clear the entire cache, follow the instructions here:
