Google Contacts Sync

I've been using Zoho for more than a year... Last month i found a few problems with my sync between Gmail Contacts and Zoho.

We have 2112 contacts in our list. I've created a brand new Google Account just to sync the contacts.

Than i went to: Setup -> Market Place -> Google (Contacts) -> Authenticate Google Contacts -> "Choose my account" and click Allow.

1) Google Contacts: My Contacts ||| Zoho CRM Contact: All Contacts
2) Sync Options: Push from Zoho CRM Contacts to Google Contacts
3) Same Contacts: Zoho CRM Contact will overwrite the Google Contact
4)Frequency: Daily
5) Field Mapping: According to my fields...
6) "Save"

And than... after waiting a NIGHT, a few of my contacts were in my google account and many of them duplicated 11 TIMES! When its done, i have 11.000 contacts in the list and MANY of them missing.

The most interesting thing is that if I choose to sync ONLY "MY CONTACTS" there is no error...

I've already tried with ZOHO SUPPORT, but off course it is not a system error... is MY fault, and they couldn't help me or solve the problem...

Can someone help me? HELP... we can't work without our cell phone!

Thanks
