tap groups on the top left, and make sure everything is checked..
Did that already. But IIRC one of the options to check was contacts "on my iPhone" but I don't see that option now.
It's ridiculous, why did I have to lose my most important contacts... I had a group of over 70 email addresses which I had to send out emails for work that's gone now
it will probably take me a good hour to put together again.
