Duplicating google contacts each time eMclient starts

I experience problems with eMclient syncing with google contacts. eMclient keeps duplicating several contacts. Out of my 500 contacts each time I open eMclient I notice several contacts that are duplicated. From 8 up to 20 times the same contact! At three or more contacts per opening… And each time I try to remove the duplicated ones I receive a message: cannot remove them. Although they are removed for the moment. Can someone help?

Hi, are you experiencing this behaviour in newest version? If so have you tried using deduplicator tool?
