Mine is doing that. It calls the next person in my contact list. I posted a thread about it with no reply. Apparently its just you and me. And unfortunately deleting and restarting the widget didn't help for me.
Did you try "un-favoriting" your contacts and redoing it?
My issue with the faves widget is when I first started adding photo id's to it ~ somehow - for some reason - it duplicated all the contacts in my phone :icon_eek: ... I started to go through and delete the dupes - and it re-created the ones I deleted ... so I started all over (deleting the dupes again) and again - it re-created the ones I deleted *sigh* ... I have 300+ contacts so it sort of became a problem ... I turned off wi-fi, mobile, roaming - everything and it finally quit, thank goodness.
First widget I trashed when I bought this thing. Never bothered with it or even thought about it. I use Animated Widget for contacts if I need to have a widget (really only use my home and GF's number on it). Otherwise I replace the entire blur/verizon contacts with GO Contacts and set my favorites through the Google account.
