Samsung Galaxy S3 — Incoming Calls No Longer Being Logged

I have had the S3 for 7 months. The incoming calls were logged until a month ago.

Now they are no longer being logged.

I played with the view settings and can see incoming calls older than a month ago.

I can incoming text messages.

But it looks like incoming calls are simply not being logged. Starting a month ago.

I can't find any settings to control what calls are being logged.

Any ideas?

All help appreciated
