Contacts search bug

When I open Contacts I can see them listed but when I start a search for a contact that i know is my database I will get "No results". My workaround is to tap "Groups" and then "Done" and then it will search normally. I use Circleback to sync my various accounts. In fact Circleback is the only group checked otherwise I would see many duplicates. I am posting this to Circleback as well.
