Double last name when importing contacts

Double last name when importing contacts

When I imported my contacts from Google, Zoho added everyone's last name to their first name, and still kept the last name filed.

Example contact: John Doe
Example import: John Doe Doe

This is what the new first name looks like: John Doe
And the last name: Doe
Result: John Doe Doe

This happened for all 600+ contacts. I don't really have time to manually fix every single one. Any one have suggestions?

Thanks!
