"no Title" on channel banner

Brought a Tivo Roamio from a place where it had been working to existing residence to replace older Premier. Used existing cable card and checked with cable company (Cox) to make sure it was paired. Connected to Tivo Service and the wireless network and everything works fine, except when you change channels, the banner says "No Title", instead of giving program information. What to do?
