Contact list doesn't show whatsapp/gtalk information

Hello,

First of all, all the contacts I mention here are stored as google contacts (not sim contacts) and they all have whatsapp and gtalk.

With some contacts (not all) when I go to the phone contacts list and I click on it's avatar, a pop-up with contact options appears. The options are: call, sms, e-mail, but it doesn't show me whatsapp and gtalk! But I can see them from whatsapp/gmail.

A contact was showing gtalk option but when I changed info about the contact (not the gmail) the option disappeared.... but, I rebooted the phone and then the gtalk option appeared.
I still have contacts without the whatsap/gmail contact option.

Is there anything I have to update/sync?

Thanks.
