Followed instructions for replacing icon. Reverted back to 1 contact.
It worked so I proceeded to customize portion of the Contact page text (just the reference to email address). I went back to the Home page and the icon was gone. So, deleted the custom text attempt (not related but didn’t want to have partial start). There is NO icon for contact and footer has returned.
