Removing a contact from "Frequently contacted" on Hangout (formerly Google Talk) app

After the recent update to v.1.0.1.678536 on my Nexus S, I see that it is automatically listing few contacts as "frequently contacted", I don't want to see certain people on that list, and there is no way to remove someone from the "Frequently contacted" list through mobile UI. I have tried the following: 1) From the Web UI, I have set that contact to "Never Show" 2) I blocked that contact from the Web UI None of these seems to work. any suggestions?
