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 3 or 4 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?
