You should clarify how you are entering the addresses. We have nothing to go
on.
I would guess you are using autocompletion rather than your contacts.
Are you?
If so, 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:
