For some reason a subset of my Google Contacts are being moved from the My Contacts list to the Other Contacts list. Unfortunately this has the effect of removing them from my iPhone as I have them synced, and only the My Contacts list is synced. It has happened three or four times in the last few months. It affects about 50 of my 160 contacts.
It seems to happen after I make minor changes to contacts on my phone - last night I added a number to a single contact, and today I noticed that the contacts were missing.
Any ideas on what is causing this and how to fix it?
