T46G Error Adding to Local Blacklist

I am trying to add to the Blacklist from the Call History and get the error “Group Not Existed”

T46G – 28.71.193.8

1. Press “History” soft key
2. Scroll to number I want to Blacklist
3. Press “Option” soft key
4. Scroll Down to “Add to Blacklist”
5. Press “OK”
6. View “Add to Blacklist” screen
7. Press keys to add a Name
8. Press “Save”
9. Receive “Group Not Existed” error

I get the same error if I try to “Add to Contacts” from the History.

Suggestions?

Thanks!
