Hide phone number from yahoo mail avatar

[Mitch Essence]

Guys, opening up the email inbox, to the right below
my avatar shows my home phone number.


It is not verified and on account security/info there is no option
to delete next to it.

Is there another way to remove it cause really at this point
i would prefer if they didnt't have to call me in order to verify it
after in which case i imagine the delete option may be available...

Thanks!
Mitch.
