I have my contacts saved up to google contacts, when my phone pulls them from google it links contacts that have no relationship together - so Person X with Person Y. It makes a real mess as calls/text dont match up with who's calling due to these links. When I go into a contact that has this issue i can see 2 google symbols in connections and the Person X and Person Y that have been linked ( In google Contacts its fine - no links). If I disconnect the incorrect link its fine, but I have about 100 incorrectly forming connections (google ones!). Deleted the cache/data storage for contacts and resynced but still issue still occurs.

Has anyone else had the same problem or know how to help?
Much appreciated
